 ## Creating a regular release
 
-1. Create a [new release](https://github.com/lightbend/genjavadoc/releases/new) with:
-  * `git tag -a -m 'Release v0.18' v0.18`
-  * title and release description including notable changes
-2. This triggers a Github Action build that should test, build and publish to sonatype, and then close and release the repository to Maven Central.

 ## Back-releasing for a new Scala version
 
 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
-  * `main`, if no features or bug fixes were merged to the main branch since the latest release. In this case create a tag recording you released from this commit, e.g. `git tag -a -m 'Release 0.18 for Scala 2.12.18' v0.18_2.12.18; git push --tags`.
+  * `main`, if no features or bug fixes were merged to the main branch since the latest release. In this case create a tag recording you released from this commit, e.g. `git tag -a -m 'Release 0.18 for Scala 2.12.19' v0.18_2.12.19; git push --tags`.
   * tag, if the main branch 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 `ThisBuild / version := "0.18"` which sets the version to be back-released. This will override the automatic version derivation from the git history. Alternatively you can `set ThisBuild / version := ...` in the command line.
-1. Publish the release by running `SONATYPE_USERNAME=xxx SONATYPE_PASSWORD=xxx sbt clean ++2.12.18 publishSigned sonatypeBundleRelease` (with the appropriate credentials and scala version). You will need Sonatype OSS repository rights to publish under `com.typesafe` organisation.

 It would be nice to have a way to backpublish through GitHub Actions instead of using our laptops. If interested in pursuing this possibility, see https://github.com/lightbend/genjavadoc/issues/333 and https://github.com/sbt/sbt-ci-release/issues/102
 
-Note that the instructions above suggest pushing a tag. Pushing the tag will cause sbt-ci-release to attempt to publish incorrect artifacts. It might be better not to push the tag at all? :shrug:
