 If you want to trigger a release quickly without manually checking deps or whatever, you can simply run the Github workflow locally:
 
 ```sh
-git checkout master && git pull && git checkout devel && git pull && git merge master && git merge devel
+git checkout main && git pull
 # yarn add -g act # @see https://github.com/nektos/act
 act # this will run the same steps as the release basically
 yarn lerna publish # --force-publish
