 # mailcow-scripts
 
-Scripts to help manage mailcow-dockerized installations
+A few scripts to help manage your mailcow-dockerized installation.  I'll be adding to this repo as I find more common administrative tasks that can be easily scripted and automated.
+
+## scripts
+
+### mail_cleanup.sh
+
+Delete messages in the *Junk* and *Trash* folders that are older than a certain amount of days.  Usage details in the [wiki here](https://#).
+
+### mail_prune.sh
+
+Delete messages from all mailboxes that are older than a certain number of days, provided those messages are *READ* and *UNflagged*.  Usage details in the [wiki here](https://#).
+
+That's all for now!
