+## Run With Docker
+
+Use Docker Compose from the repository root:
+
+```bash
+docker compose up --build sync-server
+```
+
+Or build the image directly:
+
+```bash
+docker build -f apps/sync-server/Dockerfile -t obsidian-sync-server .
+docker run --rm -p 8787:8787 -v obsidian-sync-data:/app/data obsidian-sync-server
+```
+
+The compose setup binds port `8787` by default and stores durable state in a named Docker volume called `obsidian-sync-data`.

 ## Environment Variables
 
 - `PORT`: overrides the default HTTP port.
 - `SYNC_DATA_DIR`: overrides the default data directory. If omitted, the server writes data under `./data` from the workspace root.
+- `OBSIDIAN_SYNC_PORT`: optional compose override for the host port published by `compose.yaml`.

 - Request logs include a response header named `x-request-id` for correlating client and server failures.
 - The current storage backend is file-based. It is durable for a single-node deployment but not yet designed for clustered or high-availability hosting.
 - The plugin updates local sync state after each accepted push batch and each applied pull page, which lets interrupted sync runs resume from the last durable checkpoint.
+- The Docker image includes a health check against `/health` and stores runtime data in `/app/data`.
