+
+Because SvelteKit is a pain in the ass to build in a container, and processes secrets at build time,
+there is no pre-built frontend image available.
+If you don't want to build images on your server, I recommend running the frontend outside of Docker.
+This is preconfigured in `docker-compose.prebuilt.yml`: the backend, database, and rate limiter will run in Docker,
+while the frontend is run as a normal, non-containerized service.
 
 1. Copy `docker/config.example.ini` to `docker/config.ini`, and change the settings to your liking.
 2. Copy `docker/proxy-config.example.json` to `docker/proxy-config.json`, and do the same.
-3. Copy `docker/frontend.example.env` to `docker/frontend.env`, and do the same.
-4. Build with `docker compose build`
-5. Run with `docker compose up`
+3. Run with `docker compose up -f docker-compose.prebuilt.yml`
+
+The backend will listen on port 5001 and metrics will be available on port 5002.
+The rate limiter (which is what should be exposed to the outside) will listen on port 5003.
+You can use `docker/Caddyfile` as an example for your reverse proxy. If you use nginx, good luck.
+
+# Running with Docker (local builds)
+
+In order to run *everything* in Docker, you'll have to build every container yourself.
+The advantage of this is that it's an all-in-one solution, where you only have to point your reverse proxy at a single container.
+The disadvantage is that you'll likely have to build the images on the server you'll be running them on. 
+
+1. Configure the backend and rate limiter as in the section above.
+2. Copy `docker/frontend.example.env` to `docker/frontend.env`, and configure it.
+3. Build with `docker compose build -f docker-compose.local.yml`
+4. Run with `docker compose up -f docker-compose.local.yml`
 
 The Caddy server will listen on `localhost:5004` for the frontend and API,
 and on `localhost:5005` for the profile URL shortener.
