 ## Using images in GitHub Actions
 To use the image in GitHub Actions, you should first verify the attestation of the image and reference the image by the digest
 For CI and release pipelines, you should set verify_published_from_main_image to ensure that only images published from main are used.   
 ```

 It is important that:
-- the image specified uses the tag starting githubactions-
 - there is `options: --user 1001:1001 --group-add 128` below image to ensure it uses the correct user id and is added to the docker group
 - the default shell is set to be bash
 - the first step copies .tool-versions from /home/vscode to $HOME/.tool-versions
