Read text when repository image files change
Use a repository-content trigger to turn changed screenshots, diagrams, or scanned documents into a readable update automatically.
Trigger
Repository Content Changed
Triggers when the content of a file or directory in a GitHub repository changes. Monitors a specified path within a repository on a given branch or tag. For a single file, fires ``content_changed`` when the file is modified. For a directory, fires ``content_changed``, ``content_added``, or ``content_removed`` for modified, new, or deleted entries respectively. content.
Action
