+# Release process
+
+1. Create a release commit. This includes specific updated files:
+
+   1. Cargo.toml (Bump the version using [semver] standards)
+   1. Cargo.lock (This is usually updated automatically with the `cargo`
+      CLI tool)
+   1. Make sure the changes for the new release exist under
+      `CHANGELOG.md`. This should already exist since changes done in
+      GitHub Pull Requests should include updates to the `CHANGELOG.md`.
+      If this doesn't exist, the release will fail.
+   1. Change `CHANGELOG.md` `## Unreleased` to `## [x.x.x] - YYYY-MM-DD`
+      where `x.x.x` is the new Tinty version specified in the
+      `Cargo.toml` file and the link to `[x.x.x]` at the bottom of the
+      `CHANGELOG.md` file and compare it with the previously released
+      version, eg:
+
+      ```md
+      [0.22.0]: https://github.com/tinted-theming/tinty/compare/v0.21.1...v0.22.0
+      ```
+
+   1. Run `cargo about generate about.hbs > LICENSES-THIRD-PARTY.md` to
+      update the third party licenses. (`cargo install cargo-about` if
+      you don't have it installed)
+   1. Create a commit with the 3 changed files titled `Release x.x.x`
+      where `x.x.x` is the new Tinty version specified in the
+      `Cargo.toml` file
+
+1. Push the commit or create a Pull Request and merge
+1. Once the CI tests have passed, run the [Release GitHub action]. This
+   will automatically do the following:
+
+   1. Add a Git tag to the release commit with the new
+      version number
+   1. Create a release under [GitHub releases] with the changes
+      mentioned in `CHANGELOG`
+   1. Generate the various binaries and add it to the GitHub release
+1. Run the [homebrew-tinted] [Update CLI tool GitHub
+   action] and specify `tinty` as the action input value. This will
+   update the version for [Homebrew]
