-          This is an empty workflow file located in the main branch of your
-          repository. It serves as a testing ground for new GitHub Actions on
-          development branches before merging them to the main branch. By
-          defining and overloading this workflow on your development branch,
-          you can test new actions without affecting your main branch, ensuring
-          a smooth integration process once the changes are ready to be merged.
-
-          Usage:
-          
-          1. In your development branch, modify the sandbox.yml workflow file
-             to include the new actions you want to test. Make sure to commit
-             the changes to the development branch.
-          2. Navigate to the 'Actions' tab in your repository, select the
-             '~Sandbox' workflow, and choose your development branch from the
-             branch dropdown menu. Click on 'Run workflow' to trigger the
-             workflow on your development branch.
-          3. Once you have tested and verified the new actions in the Sandbox
-             workflow, you can incorporate them into your main workflow(s) and
-             merge the development branch into the main branch. Remember to
-             revert the changes to the sandbox.yml file in the main branch to
-             keep it empty for future testing.
