+## Docker
+
+This project has first-class Docker support. I prefer to not pull my images from a repository, as that leaves one vulnerable to supply chain attacks. To build the Docker image, simply run `docker build -t lapi:latest .` in the repository directory.
+
+I am using [Alpine](https://hub.docker.com/_/alpine/) as a base image, and the application is built using the `x86_64-unknown-linux-musl` [build target](https://blog.rust-lang.org/2023/05/09/Updating-musl-targets.html).
+
+A sample `docker-compose.yml` file is also included.
+
+On my home server, this service uses 964 KB of RAM with my license database, so it is lightweight.
