+## Releasing
+
+To start a release, trigger [this workflow](https://github.com/n8n-io/n8n/actions/workflows/release-create-pr.yml) with the SemVer release type, and select a branch to cut this release from. This workflow will then
+
+1. Bump versions of packages that have changed or have dependencies that have changed
+2. Update the Changelog
+3. Create a new branch called `release/${VERSION}`, and
+4. Create a new pull-request to track any further changes that need to be included in this release
+
+Once ready to release, simply merge the pull-request.
+This triggers [another workflow](https://github.com/n8n-io/n8n/actions/workflows/release-publish.yml), that will
+
+1. Build and publish the packages that have a new version in this release
+2. Create a new tag, and GitHub release from squashed release commit
+3. Merge the squashed release commit back into `master`
+
 ## Create custom nodes
 
 Learn about [building nodes](https://docs.n8n.io/integrations/creating-nodes/) to create custom nodes for n8n. You can create community nodes and make them available using [npm](https://www.npmjs.com/).
