 ## How to release this library
 
-Beta releases from a WIP branch can be deployed Maven. To do this, start sbt with
-
-`sbt -DRELEASE_TYPE=beta`
-
-In beta mode, when you follow the remaining instructions, you'll be prompted to confirm that you intend to put out a
-beta release and if so, the version number should take the form of `x.y.z.beta.n`. While making beta releases you 
-should always update the next version to reflect the beta status of the code when prompted, i.e. don't just let it 
-revert to -SNAPSHOT which it will want to do by default. 
-
-When making a prod release once your changes have been through the PR process and are merged to the main/master branch, 
-checkout the main/master branch and start sbt as normal (without the -DRELEASE_TYPE parameter) and run
-
-```sbtshell
-release cross
-```
-
-Following a successful production release, the version details are automatically committed and pushed back to github.
+Releases are done using gha-scala-library-release-workflow release process.
+The details are here: https://github.com/guardian/gha-scala-library-release-workflow/blob/main/docs/making-a-release.md
