+# Purpose {{{
+## Create a temp file (to monitor) if an upgrade is available for Jellyfin
+## project on Github.
+## It's based on the Jellyfin URL site to get the current version.
+## How-to use {{{
+### 1. Needs releasetags script, in the same directory
+### cf. https://git.101010.fr/gardouille-dotfiles/scripts/github/releasetags
+# wget https://git.101010.fr/gardouille-dotfiles/scripts/raw/branch/master/github/releasetags
+### 2. Create a cron job with Jellyfin URL as first argument, eg.
+#00 20 * * * root /opt/repos/ipr.scripts/github/check_jellyfin_update https://jellyfin.domain.tld:port/web/index.html
+### 3. Monitor the temp file : /tmp/.github.jellyfin.upgrade
+# Or enable MAILTO in cronjob and edit the script to print a message.
+# Or send a mail.
