If your environment is linked to a git branch primarily for documentation, it's recommended to push your changes to git once you've successfully deployed elements. This process can be streamlined into a single action by clicking the Deploy&Push button, found in the deployment preview. The git commit message will automatically include all pertinent deployment details, along with a comprehensive list of all impacted NACL files.
As an alternative, you also have the option to deploy without pushing to git and push at a later time.
