 Guidelines for those with write access to rodio. Adhere to them as long as makes
 sense. This is a work in progress, more might follow as we get to know
 what works. 
 
 Please feel free to open an issue and discuss these if you have a suggestion.

+## Release Procedure
+
+The project is built automatically by a GitHub action when a new revision is pushed to the master branch.
+The crate is published by triggering `.github/workflows/manual.yml` GitHub action.
+After the crate is successfully published a new git tag is created in the repository.
+
+So to publish a new version
+1. Update `project.version` field in `Cargo.toml`.
+2. Push the changes to the `master` branch.
+3. Wait until GitHub build job completes successfully.
+4. [On the Actions page](https://github.com/RustAudio/rodio/actions) start `.github/workflows/manual.yml`.
