+# Terraria tMod docker-compose
+
+Terraria tModLoader server.  Used for Calamity Mod in my case.
+
+Image used: https://github.com/Rfvgyhn/tmodloader-docker (Stale, building updated PR fork for latest)
+
+## Optional notify container for non 24/7 servers
+
+Notify container for discord, dead simple webhook message poster to notify if server is up/down.  Include a MSG with your hours.
+
+Edit your crontab (`crontab -e`) with hours you what your server to maintain. Slightly odd to not just do 24/7 but I believe it encourage more group play if you set server hours.
+
+``` crontab
+PATH=/usr/local/bin:/usr/bin:/bin
+45 20 * * 2-5  /home/a/game-server-stacks/terraria-tmod/online.sh
+0 0 * * 3-6    /home/a/game-server-stacks/terraria-tmod/offline.sh
