 ### Using Docker-Compose
 
-The [`docker-compose.yml`](./docker-compose.yml) file in this repository is
-sufficient to run taskchampion-sync-server, including setting up TLS

 You will need a server with ports 80 and 443 open to the Internet and with a
 fixed, publicly-resolvable hostname. These ports must be available both to your
 Taskwarrior clients and to the Lets Encrypt servers.

+TASKCHAMPION_SYNC_SERVER_CLIENT_ID=your-client-id \
+docker compose up
 ```
 
+The `TASKCHAMPION_SYNC_SERVER_CLIENT_ID` limits the server to the given client
+ID; omit it to allow all client IDs.

 It can take a few minutes to obtain the certificate; the caddy container will

+1. Update the docker image in `docker-compose.yml` to refer to the new version.

+1. Run `cargo build --release`
+1. Commit the changes (Cargo.lock will change too) with comment `vX.Y.Z`.
+1. Run `git tag vX.Y.Z`

+1. Run `cargo publish -p taskchampion-sync-server-storage-sqlite` (and add any other new published packages here)
+1. Bump the patch version in `*/Cargo.toml` and add the `-pre` suffix. This allows `cargo-semver-checks` to check for changes not accounted for in the version delta.
+1. Run `cargo build --release` again to update `Cargo.lock`
