+# Contributing guide
+
+This page is for about contributing to conduwuit. The [development](docs/development.md) page may be of interest for you as well.
+
+If you would like to work on an [issue][issues] that is not assigned, preferably ask in the Matrix room first at [#conduwuit:puppygock.gay][conduwuit-matrix], and comment on it.
+
+### Linting and Formatting
+
+It is mandatory all your changes satisfy the lints (clippy, rustc, rustdoc, etc) and your code is formatted via the **nightly** `cargo fmt`. A lot of the `rustfmt.toml` features depend on nightly toolchain. It would be ideal if they weren't nightly-exclusive features, but they currently still are. CI's rustfmt uses nightly.
+
+If you need to allow a lint, please make sure it's either obvious as to why (e.g. clippy saying redundant clone but it's actually required) or it has a comment saying why. Do not write inefficient code for the sake of satisfying lints. If a lint is wrong and provides a more inefficient solution or suggestion, allow the lint and mention that in a comment.
+
+### Running CI tests locally
+
+conduwuit's CI for tests, linting, formatting, audit, etc use [`engage`][engage]. engage can be installed from nixpkgs or `cargo install engage`. conduwuit's Nix flake devshell has the nixpkgs engage with `direnv`. Use `engage --help` for more usage details.
+
+To test, format, lint, etc that CI would do, install engage, allow the `.envrc` file using `direnv allow`, and run `engage`.
+
+All of the tasks are defined at the [engage.toml][engage.toml] file. You can view all of them neatly by running `engage list`
+
+If you would like to run only a specific engage task group, use `just`:
+- `engage just <group>`
+- Example: `engage just lints`
+
+If you would like to run a specific engage task in a specific group, use `just <GROUP> [TASK]`: `engage just lints cargo-fmt`
+
+The following binaries are used in [`engage.toml`][engage.toml]:
+
+- [`engage`][engage]
+- `nix`
+- [`direnv`][direnv]
+- `rustc`
+- `cargo`
+- `cargo-fmt`
+- `rustdoc`
+- `cargo-clippy`
+- [`cargo-audit`][cargo-audit]
+- [`cargo-deb`][cargo-deb]
+- [`lychee`][lychee]
+
+### Matrix tests
+
+CI runs [Complement][complement], but currently does not fail if results from the checked-in results differ with the new results. If your changes are done to fix Matrix tests, note that in your pull request. If more Complement tests start failing from your changes, please review the logs (they are uploaded as artifacts) and determine if they're intended or not.
+
+If you'd like to run Complement locally using Nix, see the [testing](docs/development/testing.md) page.
+
+[Sytest][sytest] support will come soon.
+
+### Writing documentation
+
+conduwuit's website uses [`mdbook`][mdbook] and deployed via CI using GitHub Pages in the [`documentation.yml`][documentation.yml] workflow file with Nix's mdbook in the devshell. All documentation is in the `docs/` directory at the top level. The compiled mdbook website is also uploaded as an artifact.
+
+To build the documentation using Nix, run: `bin/nix-build-and-cache just .#book`
+
+The output of the mdbook generation is in `result/`. mdbooks can be opened in your browser from the individual HTML files without any web server needed.
+
+### Inclusivity and Diversity
+
+All **MUST** code and write with inclusivity and diversity in mind. See the [following page by Google on writing inclusive code and documentation](https://developers.google.com/style/inclusive-documentation).
+
+This **EXPLICITLY** forbids usage of terms like "blacklist"/"whitelist" and "master"/"slave", [forbids gender-specific words and phrases](https://developers.google.com/style/pronouns#gender-neutral-pronouns), forbids ableist language like "sanity-check", "cripple", or "insane", and forbids culture-specific language (e.g. US-only holidays or cultures).
+
+No exceptions are allowed. Dependencies that may use these terms are allowed but [do not replicate the name in your functions or variables](https://developers.google.com/style/inclusive-documentation#write-around).
+
+In addition to language, write and code with the user experience in mind. This is software that intends to be used by everyone, so make it easy and comfortable for everyone to use. 🏳️‍⚧️
+
+### Variable, comment, function, etc standards
+
+Rust's default style and standards with regards to [function names, variable names, comments](https://rust-lang.github.io/api-guidelines/naming.html), etc applies here.
+
+### Creating pull requests
+
+Please try to keep contributions to the GitHub. While the mirrors of conduwuit allow for pull/merge requests, there is no guarantee I will see them in a timely manner. Additionally, please mark WIP or unfinished or incomplete PRs as drafts. This prevents me from having to ping once in a while to double check the status of it, especially when the CI completed successfully and everything so it *looks* done.
+
+If you open a pull request on one of the mirrors, it is your responsibility to inform me about its existence. In the future I may try to solve this with more repo bots in the conduwuit Matrix room. There is no mailing list or email-patch support on the sr.ht mirror, but if you'd like to email me a git patch you can do so at `strawberry@puppygock.gay`.
+
+Direct all PRs/MRs to the `main` branch.
+
+By sending a pull request or patch, you are agreeing that your changes are allowed to be licenced under the Apache-2.0 licence and all of your conduct is in line with the Contributor's Covenant.

+conduwuit is a hard fork of Conduit which is in beta, meaning you can join and participate in most
 Matrix rooms, but not all features are supported and you might run into bugs
 from time to time.

-#### Why does this fork exist? Why don't you contribute back upstream?
-
-I now intend on contributing back as time and mental energy sees fit, but my fork still exists as a way to:
- avoid unnecessary Matrix and general developer politics
- avoid bikeshedding unnecessary or irrelevant things in upstream MRs
- Fast tracked bug fixes, performance improvements, security improvements, and new features
- Have early access to MRs that may not be suitable/acceptable for Conduit (e.g. too niche, too advanced for general users, only being blocked due to pending on contributor actions that we can fix ourselves downstream, pending Matrix spec stuff, etc)
- Support unspecced or WIP features
- Have official support for other OS's like Windows, macOS, and BSD.
- Have a **stable** testing ground for some MRs or new features and bug fixes
-
-And various other reasons that may not be listed here.

-
-### Build using a Dockerfile
-
-The Dockerfile provided by Conduit has two stages, each of which creates an image.
-
-1. **Builder:** Builds the binary from local context or by cloning a git revision from the official repository.
-2. **Runner:** Copies the built binary from **Builder** and sets up the runtime environment, like creating a volume to persist the database and applying the correct permissions.
-
-To build the image you can use the following command
-
-```bash
-docker build --tag girlbossceo/conduwuit:main .
-```
-
-which also will tag the resulting image as `girlbossceo/conduwuit:main`.
-
-
-
 ### Run

 When you have the image you can simply run it with

 ```bash
 docker run -d -p 8448:6167 \

 ## Voice communication

-In order to make or receive calls, a TURN server is required. Conduit suggests using [Coturn](https://github.com/coturn/coturn) for this purpose, which is also available as a Docker image. Before proceeding with the software installation, it is essential to have the necessary configurations in place.
-
-### Configuration
-
-Create a configuration file called `coturn.conf` containing:
-
-```conf
-use-auth-secret
-static-auth-secret=<a secret key>
-realm=<your server domain>
-```
-A common way to generate a suitable alphanumeric secret key is by using `pwgen -s 64 1`.
-
-These same values need to be set in conduit. You can either modify conduit.toml to include these lines:
-```
-turn_uris = ["turn:<your server domain>?transport=udp", "turn:<your server domain>?transport=tcp"]
-turn_secret = "<secret key from coturn configuration>"
-```
-or append the following to the docker environment variables dependig on which configuration method you used earlier:
-```yml
-CONDUIT_TURN_URIS: '["turn:<your server domain>?transport=udp", "turn:<your server domain>?transport=tcp"]'
-CONDUIT_TURN_SECRET: "<secret key from coturn configuration>"
-```
-Restart Conduit to apply these changes.
-
-### Run
-Run the [Coturn](https://hub.docker.com/r/coturn/coturn) image using 
-```bash
-docker run -d --network=host -v $(pwd)/coturn.conf:/etc/coturn/turnserver.conf coturn/coturn
-```
-
-or docker-compose. For the latter, paste the following section into a file called `docker-compose.yml`
-and run `docker-compose up -d` in the same directory.
-
-```yml
-version: 3
-services:
-    turn:
-      container_name: coturn-server
-      image: docker.io/coturn/coturn
-      restart: unless-stopped
-      network_mode: "host"
-      volumes:

+### list of features, bug fixes, etc that conduwuit does that Conduit does not:

- GitLab CI ported to GitHub Actions
- Fixed every single clippy (default lints) and rustc warnings, including some that were performance related or potential safety issues / unsoundness
- Add a **lot** of other clippy and rustc lints and a rustfmt.toml file
- Has Renovate and significantly updates all dependencies possible
- Uses proper argon2 crate instead of questionable rust-argon2 crate
- Improved and cleaned up logging (less noisy dead server logging, registration attempts, more useful troubleshooting logging, etc)
- Attempts and interest in removing extreme and unnecessary panics/unwraps/expects that can lead to denial of service or such (upstream and upstream contributors want this unusual behaviour for some reason)
- Merged and cleaned up upstream MRs that have been sitting for 6-12 months
- Configurable RocksDB logging (`LOG` files) with proper defaults (rotate, max size, verbosity, etc) to stop LOG files from accumulating so much
- Concurrency support for key fetching for faster remote room joins and room joins that will error less frequently (via upstream MR)
- Room version 11 support (via upstream MR)
- Explicit startup error/warning if your configuration allows open registration without a token or such like Synapse
- Improved RocksDB defaults to use new features that help with performance significantly, uses settings tailored to SSDs, various ways to tweak RocksDB, and a conduwuit setting to tell RocksDB to use settings that are tailored to HDDs or slow spinning rust storage.
- Revamped admin room infrastructure and commands (via upstream MR)
- Admin room commands to delete room aliases and unpublish rooms from our room directory (via upstream MR)
- Make spaces/hierarchy cache use cache_capacity_modifier instead of hardcoded small value
- Add *optional* feature flag to use SHA256 key names for media instead of base64 to overcome filesystem file name length limitations (OS error file name too long) (via upstream MR)
+Outgoing typing indicators, outgoing read receipts, **and** outgoing presence!
+
+## Performance:
+- Concurrency support for key fetching for faster remote room joins and room joins that will error less frequently
+- Send `Cache-Control` response header with `immutable` and 1 year cache length for all media requests (download and thumbnail) to instruct clients to cache media, and reduce server load from media requests that could be otherwise cached
 - Add feature flags and config options to enable/build with zstd, brotli, and/or gzip HTTP body compression (response and request)
- Add support for querying both Matrix SRV records, the deprecated `_matrix` record and `_matrix-fed` record if necessary
+- Eliminate all usage of the thread-blocking `getaddrinfo(3)` call upon DNS queries, significantly improving federation latency/ping and cache DNS results (NXDOMAINs, successful queries, etc) using hickory-dns / hickory-resolver
+- Vastly improve RocksDB default settings to use new features that help with performance significantly, uses settings tailored to SSDs, various ways to tweak RocksDB, and a conduwuit setting to tell RocksDB to use settings that are tailored to HDDs or slow spinning rust storage or buggy filesystems.
+- Add a Cargo build profile for aggressive build-time performance optimisations for release builds (1 codegen unit, no debug, fat LTO, etc, and optimise all crates with same)
+- Implement database flush and cleanup conduwuit operations when using RocksDB
+- Implement RocksDB write buffer corking and coalescing in database write-heavy areas
+- Perform connection pooling and keepalives where necessary to significantly improve federation performance and latency
+- Various config options to tweak connection pooling, request timeouts, connection timeouts, DNS timeouts and settings, etc with good defaults which also help huge with performance via reusing connections and retrying where needed
+- Implement building conduwuit with jemalloc (which extends to the RocksDB jemalloc feature for maximum gains) or hardened_malloc light variant, and produce CI builds with jemalloc for performance (Nix doesn't seem to build [hardened_malloc-rs](https://github.com/girlbossceo/hardened_malloc-rs) properly)
+- Add support for caching DNS results with hickory-dns / hickory-resolver in conduwuit (not a replacement for a proper resolver cache, but still far better than nothing)
+- Add config option for using DNS over TCP, and config option for controlling A/AAAA record lookup strategy (e.g. don't query AAAA records if you don't have IPv6 connectivity)
+- Overall significant database, Client-Server, and federation performance and latency improvements (check out the ping room leaderboards if you don't believe me :>)
+- Add config options for RocksDB compression and bottommost compression, including choosing the algorithm and compression level
+- Use [loole](https://github.com/mahdi-shojaee/loole) MPSC channels instead of tokio MPSC channels for huge performance boosts in sending channels (mainly relevant for federation) and presence channels
+- Use `tracing`/`log`'s `release_max_level_info` feature to improve performance, build speeds, binary size, and CPU usage in release builds by avoid compiling debug/trace log level macros that users will generally never use (can be disabled with a build-time feature flag)
+- Enable RocksDB async read I/O via `io_uring` by default
+
+
+## General Fixes:
+- Raise and improve all the various request timeouts making some things like room joins and client bugs error less or none at all than they should, and make them all user configurable
+- Add missing `reason` field to user ban events (`/ban`)
+- Fixed spec compliance issue with room version 8 - 11 joins (https://github.com/matrix-org/synapse/issues/16717 / https://github.com/matrix-org/matrix-spec/issues/1708)
+- Safer and cleaner shutdowns on both database side as we run cleanup on shutdown and exits database loop better (no potential hanging issues in database loop), overall cleaner shutdown logic
+- Stop sending `make_join` requests on room joins if 15 servers respond with `M_UNSUPPORTED_ROOM_VERSION` or `M_INVALID_ROOM_VERSION`
+- Stop sending `make_join` requests if 50 servers cannot provide `make_join` for us
+- Respect *most* client parameters for `/media/` requests (`allow_redirect` still needs work)
+- Increased graceful shutdown timeout from a low 60 seconds to 180 seconds to avoid killing connections and let the remaining ones finish processing
+- Return joined member count of rooms for push rules/conditions instead of a hardcoded value of 10
+- Make `CONDUIT_CONFIG` optional, relevant for container users that configure only by environment variables and no longer need to set `CONDUIT_CONFIG` to an empty string.
+- Allow HEAD and PATCH (MSC4138) HTTP requests in CORS for clients (despite not being explicity mentioned in Matrix spec, HTTP spec says all HEAD requests need to behave the same as GET requests, Synapse supports HEAD requests)
+- Resolve and remove some "features" from upstream that result in concurrency hazards, exponential backoff issues, or arbitrary performance limiters
+- Find more servers for outbound federation `/hierarchy` requests instead of just the room ID server name

+- Add workaround for [Out Of Your Element](https://gitdab.com/cadence/out-of-your-element) appservice bridge to make it functional on conduwuit (bug has already been reported)
+
+
+## Moderation:
+- (Also see [Admin Room](#admin-room) for all the admin commands pertaining to moderation, there's a lot!)
+- Add support for room banning/blocking by ID using admin command
+- Add support for serving `support` well-known from `[well_known.support]` (MSC1929)
+- Config option to forbid publishing rooms to the room directory (`lockdown_public_room_directory`) except for admins
+- Admin commands to delete room aliases and unpublish rooms from our room directory
+- For all [`/report`](https://spec.matrix.org/v1.9/client-server-api/#post_matrixclientv3roomsroomidreporteventid) requests: check if the reported event ID belongs to the reported room ID, raise report reasoning character limit to 750, fix broken formatting, make a small delayed random response per spec suggestion on privacy, and check if the sender user is in the reported room.
+- Support blocking servers from downloading remote media from, returning a 404
+- Don't allow `m.call.invite` events to be sent in public rooms (prevents calling the entire room)
+- On new public room creations, only allow moderators to send `m.call.invite`, `org.matrix.msc3401.call`, and `org.matrix.msc3401.call.member` events
+- Add support for a "global ACLs" feature (`forbidden_remote_server_names`) that blocks inbound remote room invites, room joins by room ID on server name, room joins by room alias on server name, incoming federated joins, and incoming federated room directory requests. This is very helpful for blocking servers that are purely toxic/bad and serve no value in allowing our users to suffer from things like room invite spam or such. Please note that this is not a substitute for room ACLs.
+- Add support for a config option to forbid our local users from sending federated room directory requests for (`forbidden_remote_room_directory_server_names`). Similar to above, useful for blocking servers that help prevent our users from wandering into bad areas of Matrix via room directories of those malicious servers.
+- Add config option for auto remediating/deactivating local non-admin users who attempt to join bad/forbidden rooms (`auto_deactivate_banned_room_attempts`)
+
+
+## Privacy/Security:
 - Add config option for device name federation with a privacy-friendly default (disabled)

- Add support for listening on a UNIX socket for performance and host security with proper default permissions (660)
- Add missing `destination` key to all `X-Matrix` `Authorization` requests (spec compliance issue)
- Use aggressive build-time performance optimisations for release builds (1 codegen unit, no debug, fat LTO, etc, and optimise all crates with same)
- Raise various hardcoded timeouts in codebase that were way too short, making some things like room joins and client bugs error less or none at all than they should
- Add debug admin command to force update user device lists (could potentially resolve some E2EE flukes) (`ForceDeviceListUpdates`)
- Declare various missing Matrix versions and features at `/_matrix/client/versions`
- Add support for serving server and client well-known files from conduwuit using `well_known_client` and `well_known_server` options
- Send a User-Agent on all of our requests (`conduwuit/0.7.0-alpha+conduwuit-0.1.1`) which strangely was not done upstream since forever. Some providers consider no User-Agent suspicious and block said requests.
- Safer and cleaner shutdowns on both database side as we run cleanup on shutdown and exits database loop better (no potential hanging issues in database loop), overall cleaner shutdown logic
- Allow HEAD HTTP requests in CORS for clients (despite not being explicity mentioned in Matrix spec, HTTP spec says all HEAD requests need to behave the same as GET requests, Synapse supports HEAD requests)

- webp support for images
- Support for suggesting servers to join at `/_matrix/client/v3/directory/room/{roomAlias}`

- Add basic cache eviction for true destinations when requests fail if we use a cached destination (e.g. a server has modified their well-known and we're still connecting to the old destination)
+- Uses proper `argon2` crate by RustCrypto instead of questionable `rust-argon2` crate
 - Generate passwords with 25 characters instead of 15
- Add missing `reason` field to user ban events (`/ban`)
- For all [`/report`](https://spec.matrix.org/v1.9/client-server-api/#post_matrixclientv3roomsroomidreporteventid) requests: check if the reported event ID belongs to the reported room ID, raise report reasoning character limit to 750, fix broken formatting, make a small delayed random response per spec suggestion on privacy, and check if the sender user is in the reported room.
- Support blocking servers from downloading remote media from
- Support sending `well_known` response to client logins if using config option `well_known_client`
- Send `avatar_url` on invite room membership events/changes
- Revamp example config, adding a lot of config options available (still some missing)
- Return joined member count of rooms for push rules/conditions instead of a hardcoded value of 10
- Respect *most* client parameters for `/media/` requests (`allow_redirect` still needs work)
 - Config option `ip_range_denylist` to support refusing to send requests (typically federation) to specific IP ranges, typically RFC 1918, non-routable, testnet, etc addresses like Synapse for security (note: this is not a guaranteed protection, and you should be using a firewall with zones if you want guaranteed protection as doing this on the application level is prone to bypasses).
- Support for creating rooms with custom room IDs like Maunium Synapse (`room_id` request body field to `/createRoom`)
- Assume well-knowns are broken if they exceed past 10000 characters.

+- Config option to disable incoming and/or outgoing remote read receipts
+- Config option to disable incoming and/or outgoing remote typing indicators
+- Config option to disable incoming, outgoing, and/or local presence
+- Sanitise file names for the `Content-Disposition` header for all media requests (thumbnails, downloads, uploads)
+- Return `inline` or `attachment` based on the detected file MIME type for the `Content-Disposition` and only allow images/videos/text/audio to be `inline`
+- Send secure default HTTP headers such as a strong restrictive CSP, deny iframes, disable `X-XSS-Protection`, disable interest cohort in `Permission-Policy`, etc to mitigate any potential attack surface such as from untrusted media
+
+
+## Administration/Logging:
+- Commandline argument to specify the path to a config file instead of relying on `CONDUIT_CONFIG`
+- Revamped admin room infrastructure and commands
+- Substantially clean up, improve, and fix logging (less noisy dead server logging, registration attempts, more useful troubleshooting logging, proper error propagation, etc)
+- Configurable RocksDB logging (`LOG` files) with proper defaults (rotate, max size, verbosity, etc) to stop LOG files from accumulating so much
+- Explicit startup error if your configuration allows open registration without a token or such like Synapse with a way to bypass it if needed

+# Maintaining your conduwuit setup
+
+## Moderation
+
+conduwuit has moderation through admin room commands. "binary commands" (medium priority) and an admin API (low priority) is planned. Some moderation-related config options are available in the example config such as "global ACLs" and blocking media requests to certain servers. See the example config for the moderation config options under the "Moderation / Privacy / Security" section.
+
+conduwuit has moderation admin commands for:
+- managing room aliases (`!admin rooms alias`)
+- managing room directory (`!admin rooms directory`)
+- managing room banning/blocking and user removal (`!admin rooms moderation`)
+- managing user accounts (`!admin users`)
+- fetching `/.well-known/matrix/support` from servers (`!admin federation`)
+- blocking incoming federation for certain rooms (not the same as room banning) (`!admin federation`)
+- deleting media (see [the media section](#media))
+
+Any commands with `-list` in them will require a codeblock in the message with each object being newline delimited. An example of doing this is:
+
+````
+!admin rooms moderation ban-list-of-rooms
+```
+!roomid1:server.name
+!roomid2:server.name
+!roomid3:server.name
+```
+````
+
+## Database
+
+If using RocksDB, there's very little you need to do. Compaction is ran automatically based on various defined thresholds tuned for conduwuit to be high performance with the least I/O amplifcation or overhead. Manually running compaction is not recommended, or compaction via a timer. RocksDB is built with io_uring support via liburing for async read I/O.
+
+Some RocksDB settings can be adjusted such as the compression method chosen. See the RocksDB section in the [example config](configuration.md). btrfs users may benefit from disabling compression on RocksDB if CoW is in use.
+
+RocksDB troubleshooting can be found [in the RocksDB section of troubleshooting](troubleshooting.md).
+
+## Backups
+
+Currently only RocksDB supports online backups. If you'd like to backup your database online without any downtime, see the `!admin server` command for the backup commands and the `database_backup_path` config options in the example config. Please note that the format of the database backup is not the exact same. This is unfortunately a bad design choice by Facebook as we are using the database backup engine API from RocksDB, however the data is still there and can still be joined together.
+
+To restore a backup from an online RocksDB backup:
+- shutdown conduwuit
+- create a new directory for merging together the data
+- in the online backup created, copy all `.sst` files in `$DATABASE_BACKUP_PATH/shared_checksum` to your new directory
+- trim all the strings so instead of `######_sxxxxxxxxx.sst`, it reads `######.sst`. A way of doing this with sed and bash is `for file in *.sst; do mv "$file" "$(echo "$file" | sed 's/_s.*/.sst/')"; done`
+- copy all the files in `$DATABASE_BACKUP_PATH/1` to your new directory
+- set your `database_path` config option to your new directory, or replace your old one with the new one you crafted
+- start up conduwuit again and it should open as normal
+
+If you'd like to do an offline backup, shutdown conduwuit and copy your `database_path` directory elsewhere. This can be restored with no modifications needed.
+
+Backing up media is also just copying the `media/` directory from your database directory.
+
+## Media
+
+Media still needs various work, however conduwuit implements media deletion via:
+- MXC URI
+- Delete list of MXC URIs
+- Delete remote media in the past `N` seconds/minutes
+
+See the `!admin media` command for further information. All media in conduwuit is stored at `$DATABASE_DIR/media`. This will be configurable soon.
+
+If you are finding yourself needing extensive granular control over media, we recommend looking into [Matrix Media Repo](https://github.com/t2bot/matrix-media-repo). conduwuit intends to implement various utilities for media, but MMR is dedicated to extensive media management.
+
+Built-in S3 support is also planned, but for now using a "S3 filesystem" on `media/` works. conduwuit also sends a `Cache-Control` header of 1 year and immutable for all media requests (download and thumbnail) to reduce unnecessary media requests from browsers.

+# Troubleshooting conduwuit
+
+> ## Docker users ⚠️
+>
+> Docker is extremely UX unfriendly. Because of this, a ton of issues or support is actually Docker support, not conduwuit support. We also cannot document the ever-growing list of Docker issues here.
+>
+> If you intend on asking for support and you are using Docker, **PLEASE** triple validate your issues are **NOT** because you have a misconfiguration in your Docker setup.
+>
+> If there are things like Compose file issues or Dockerhub image issues, those can still be mentioned as long as they're something we can fix.
+
+## Rocksdb / database issues
+
+#### Direct IO
+
+Some filesystems may not like RocksDB using [Direct IO](https://github.com/facebook/rocksdb/wiki/Direct-IO). Direct IO is for non-buffered I/O which improves conduwuit performance, but at least FUSE is a filesystem potentially known to not like this. See the [example config](configuration.md) for disabling it if needed. Issues from Direct IO on unsupported filesystems are usually shown as startup errors.
+
+#### Database corruption
+
+If your database is corrupted and is failing to start (e.g. checksum mismatch), it may be recoverable but careful steps must be taken, and there is no guarantee it may be recoverable.
+
+RocksDB has the following recovery modes:
+
+- `TolerateCorruptedTailRecords`
+- `AbsoluteConsistency`
+- `PointInTime`
+- `SkipAnyCorruptedRecord`
+
+By default, conduwuit uses `TolerateCorruptedTailRecords` as generally these may be due to bad federation and we can re-fetch the correct data over federation. The RocksDB default is `PointInTime` which will attempt to restore a "snapshot" of the data when it was last known to be good. This data can be either a few seconds old, or multiple minutes prior. `PointInTime` may not be suitable for default usage due to clients and servers possibly not being able to handle sudden "backwards time travels", and `AbsoluteConsistency` may be too strict.
+
+`AbsoluteConsistency` will fail to start the database if any sign of corruption is detected. `SkipAnyCorruptedRecord` will skip all forms of corruption unless it forbids the database from opening (e.g. too severe). Usage of `SkipAnyCorruptedRecord` voids any support as this may cause more damage and/or leave your database in a permanently inconsistent state, but it may do something if `PointInTime` does not work as a last ditch effort.
+
+With this in mind:
+- First start conduwuit with the `PointInTime` recovery method. See the [example config](configuration.md) for how to do this using `rocksdb_recovery_mode`
+- If your database successfully opens, clients are recommended to clear their client cache to account for the rollback
+- Leave your conduwuit running in `PointInTime` for at least 30-60 minutes so as much possible corruption is restored
+- If all goes will, you should be able to restore back to using `TolerateCorruptedTailRecords` and you have successfully recovered your database
+
+## Media
+
+#### "File name too long"
+
+If you are running into the "file name is too long" OS error for media requests, your filesystem cannot handle file name lengths >=255 characters. This is unfortuntely due to Conduit (upstream) using base64 for file name keys which is very problematic for some filesystems as the base64 input is untrusted and long file names or specific inputs can cause this. If you would like to avoid this, you may build conduwuit yourself with the `sha256_media` feature. **This will lose database compatibility with upstream**.
+
+## Debugging
+
+Note that users should not really be debugging things. If you find yourself debugging and find the issue, please let us know and/or how we can fix it. Various debug commands can be found in `!admin debug`.
+
+#### Debug/Trace log level
+
+conduwuit builds without debug or trace log levels by default for at least performance reasons. This may change in the future and/or binaries providing such configurations may be provided. If you need to access debug/trace log levels, you will need to build without the `release_max_log_level` feature.
+
+#### Changing log level dynamically
+
+conduwuit supports changing the tracing log environment filter on-the-fly using the admin command `!admin debug change-log-level`. This accepts a string **without quotes** the same format as the `log` config option.
+
+#### Pinging servers
+
+conduwuit can ping other servers using `!admin debug ping`. This takes a server name and goes through the server discovery process and queries `/_matrix/federation/v1/version`. Errors are outputted.
+
+#### Allocator memory stats
+
+If using jemalloc (for now) and built with jemallocator's `stats` feature, you can see conduwuit's jemalloc memory stats by using `!admin debug memory-stats`

 # Setting up TURN/STURN

-## General instructions
+In order to make or receive calls, a TURN server is required. conduwuit suggests using [Coturn](https://github.com/coturn/coturn) for this purpose, which is also available as a Docker image.

-* It is assumed you have a [Coturn server](https://github.com/coturn/coturn) up and running. See [Synapse reference implementation](https://github.com/matrix-org/synapse/blob/develop/docs/turn-howto.md).
+### Configuration

-## Edit/Add a few settings to your existing conduit.toml
+Create a configuration file called `coturn.conf` containing:
+
+```conf
+use-auth-secret
+static-auth-secret=<a secret key>
+realm=<your server domain>
+```
+A common way to generate a suitable alphanumeric secret key is by using `pwgen -s 64 1`.
+
+These same values need to be set in conduwuit. You can either modify conduwuit.toml to include these lines:

-## Apply settings
+or append the following to the docker environment variables dependig on which configuration method you used earlier:

-Restart Conduit.
+```yml
+CONDUIT_TURN_URIS: '["turn:<your server domain>?transport=udp", "turn:<your server domain>?transport=tcp"]'
+CONDUIT_TURN_SECRET: "<secret key from coturn configuration>"
+```
+
+Restart conduwuit to apply these changes.
+
+### Run
+Run the [Coturn](https://hub.docker.com/r/coturn/coturn) image using
+```bash
+docker run -d --network=host -v $(pwd)/coturn.conf:/etc/coturn/turnserver.conf coturn/coturn
+```
+
+or docker-compose. For the latter, paste the following section into a file called `docker-compose.yml`
+and run `docker compose up -d` in the same directory.
+
+```yml
+version: 3
+services:
+    turn:
+      container_name: coturn-server
+      image: docker.io/coturn/coturn
+      restart: unless-stopped
+      network_mode: "host"
+      volumes:
+        - ./coturn.conf:/etc/coturn/turnserver.conf
+```
+
+To understand why the host networking mode is used and explore alternative configuration options, please visit [Coturn's Docker documentation](https://github.com/coturn/coturn/blob/master/docker/coturn/README.md).
