-To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).

 To generate documentation run `yard`. To view undocumented files run `yard stats --list-undoc`.
 
+## Releases
+
+Releases are driven by git tags. The version lives in `lib/slayer/version.rb`, and the gemspec reads `Slayer::VERSION`.
+
+```bash
+bundle install
+bin/release patch # or: minor, major
+```
+
+To publish an RC for a specific version:
+
+```bash
+bin/release rc 1.2.0
+```
+
+This sets the version to `1.2.0-rc` and tags it as `v1.2.0-rc`.
+
+Prereleases can also use `bump`'s native `pre` increment:
+
+```bash
+bin/release pre
+```
+
+`pre` cycles prerelease labels in order: `alpha`, `beta`, `rc`, then the final version. For example, `1.2.0-rc` becomes `1.2.0`, tagged as `v1.2.0`.
+
+`bin/release` uses `bump`, commits the version file, creates a `v<version>` tag, pushes the branch, and pushes the tag.
+
+GitHub Actions publishes only when a `v*` tag is pushed. The publish workflow builds the gem, pushes it to RubyGems with `RUBYGEMS_API_KEY`, and creates a GitHub release with the built gem attached. Tags containing a prerelease suffix, such as `v1.2.0-rc`, are marked as prereleases on GitHub.
