 ## Installation & Deployment
 
-### Docker (Recommended)
+### Docker (Recommended for self-hosting)
 
-The project includes a multi-arch Docker build (amd64/arm64).
+A pre-built multi-arch image (amd64/arm64) is automatically published to the Gitea registry on every release.
+
+**1. Authenticate first** (only needed once, saves credentials to `~/.config/strava-mcp-server/config.env`):
+
+```bash
+uvx --from strava-mcp-server-hnrx auth
+```
+
+**2. Pull and run the image:**
+
+```bash
+# Pull the latest release
+docker pull git.hnrx.net/hnrx/strava-mcp-server:latest
+
+# Run with your credentials from the config file
+docker run --rm -p 8000:8000 \
+  -e STRAVA_CLIENT_ID=<your_client_id> \
+  -e STRAVA_CLIENT_SECRET=<your_client_secret> \
+  -e STRAVA_REFRESH_TOKEN=<your_refresh_token> \
+  -e MCP_TRANSPORT=http \
+  git.hnrx.net/hnrx/strava-mcp-server:latest
+```
+
+Or using your config file directly:
+
+```bash
+docker run --rm -p 8000:8000 \
+  --env-file ~/.config/strava-mcp-server/config.env \
+  -e MCP_TRANSPORT=http \
+  git.hnrx.net/hnrx/strava-mcp-server:latest
+```
+
+> **Tip:** Pin to a specific version for stability, e.g. `git.hnrx.net/hnrx/strava-mcp-server:v0.2.0`
