+# Workflow documentation
+
+## `ci.yml`
+
+Defines the Continuous Integration workflow for merging into the `master` branch.
+
+## Releases
+
+The workflows in this repository automate various things around releases.
+The functionality is composed in such a way that a human can easily start the workflow at various points, i.e. instead of being an all-or-nothing automation, we can step in where necessary.
+
+### Preview release
+
+We have a rolling tag `preview` that always points to HEAD of `master`.
+The [preview-release.yml](./preview-release.yml) workflow moves this tag to latest HEAD every time a PR gets merged.
+It also creates a corresponding GitHub "pre-release".
+
+### Building release binaries and attaching changelog
+
+Whenever a new release is created, the [build-release-binaries.yml](build-release-binaries.yml) workflow will build the `swap` and `asb` binaries in release mode and attach them to the release as artifacts.
+
+Because this workflow is triggered on every release, it works for:
+
+- automatically created `preview` releases
+- releases created through the GitHub web interface
+- releases created by merging release branches into `master`
+
+### Making a new release
+
+To create a new release, one has to:
+
+- Create a new branch
+- Update the version in the [swap/Cargo.toml](../../swap/Cargo.toml) manifest file
+- Update the Changelog (convert `Unreleased` section to a release)
+- Make a commit
+- Open and merge a PR
+- Create a release from the resulting merge commit
+
+To avoid errors in this process, we can automate it.
+The [draft-new-release.yml](./draft-new-release.yml) workflow allows the user specify the desired version and the workflow will then open a PR that automates the above.
+
+The created branch will follow the naming of `release/X.Y.Z` for the given version.
+
+Any time a PR with such a branch name is merged, the [create-release.yml](./create-release.yml) workflow kicks in and creates a new release based on the resulting merge commit.
+
+Because these two workflows are de-coupled, a user is free to create a release branch themselves if they wish to do so.
+They may also side-step both of these workflows by creating a release manually using the Github web interface.
