 Alternatively, you can run on other event types such as `on: [push]`. In that case the action will lint the push event's commit(s) instead of linting commits from a pull request. You can also combine `push` and `pull_request` together in the same workflow.
 
-**Note**: It's necessary that you specify the `fetch-depth` argument to `actions/checkout@v2` step. By default they fetch only latest commit of the branch, but we need more commits since we validate a range of commit messages.
