+# The YunoHost-Apps organisation offers a template Action to run this script periodically
+# Since each app is different, maintainers can adapt its contents so as to perform
+# automatic actions when a new upstream release is detected.
+
+#=================================================
+# FETCHING LATEST RELEASE AND ITS ASSETS
+#=================================================
+
+# Fetching information

+
+# Later down the script, we assume the version has only digits and dots
+# Sometimes the release name starts with a "v", so let's filter it out.
+# You may need more tweaks here if the upstream repository has different naming conventions.
