 # Development setup
-This project is built using Go 1.18.1.
+
+Install the latest version of Go from https://go.dev/doc/install.
 
 To run the command line:
+
 ```
 go run ./cmd/av [subcommand/flags...]
 ```
+
+# Release
+
+To create a release, create a tag with the desired version and push to GitHub.
+
+```
+# Change the version as appropriate
+TAG="v0.0.0"
+
+git tag "$TAG"
+git push origin tags/"$TAG"
+```
+
+This will automatically trigger [Goreleaser](https://goreleaser.com/) (as part
+of the
+[`release.yml` workflow](https://github.com/aviator-co/av/blob/master/.github/workflows/release.yml))
+which will create a GitHub release and build and publish binaries to Homebrew
+and Scoop.
