 ## Installation
 
+To have Continuwuity working, you'll generally need to:
+
+1. Have a domain name pointing to your server's IP address - we will be using `example.com` in our guides.
+2. Download or build Continuwuity from your preferred source.
+3. Configure Continuwuity via the config file or environment variables. See the [Configuration](./configuration.mdx) page for more.
+4. Employ a reverse proxy in front of Continuwuity - we will be using Caddy for our guides.
+5. And finally, start the Continuwuity service.
+
 Navigate to the pages in this section that corresponds to your desired method of deploying Continuwuity, and follow the instructions there.
