 It is often the case when this compiler plugin needs to be released for a newly released Scala version. For this the process is the following:
 
 1. Checkout the version that is to be back-released, which would be
-  * master, if no features or bug fixes were merged to master since the latest release
+  * master, if no features or bug fixes were merged to master since the latest release. In this case create a tag recording you released from this commit, e.g. `git tag v0.16_2.12.13; git push --tags`.
   * tag, if the master has unreleased features or bug fixes. In this case you will need to cherry pick the commit that adds support for the new Scala version.
-1. Create a file `version.sbt` containing `version in ThisBuild := "0.11"` which sets the version to be back-released. This will override the automatic version derivation from the git history. Alternatively you can `set version in ThisBuild := ...` in the command line.
