+## Deployment
+
+This project uses Github actions to deploy changes pushed to the `main` branch to fly.io.
+
+The deployment pipeline is defined in [.github/workflows/deploy.yml](.github/workflows/deploy.yml)
+and [fly.toml](fly.toml). Authentication to fly.io is enabled by
+a `FLY_API_TOKEN` [repository secret](https://docs.github.com/en/actions/security-guides/encrypted-secrets#creating-encrypted-secrets-for-a-repository).
+
+The following commands were used to initialize the fly application.
+
+```shell
+fly apps create awesome-radio-1ae3
+fly secrets set SESSION_SECRET=$(openssl rand -hex 32) --app awesome-radio-1ae3
+fly volumes create data --size 1 --app awesome-radio-1ae3
+fly scale memory 512 --app awesome-radio-1ae3
+```
