autodeploygit_ynh/.github/workflows/updater.yml

# This workflow allows GitHub Actions to automagically update your app
# whenever a new upstream release is detected.
# You need to enable Actions in your repository settings.
# This file should be enough by itself, but feel free to tune it to your needs.
# It calls updater.sh, which is where you should put the app-specific update steps.
