 This is a 'fork' of [Chest Tracker](https://modrinth.com/mod/chest-tracker) for 1.21.1 that's [CivMC](https://civmc.net)
 legal.
 
+## Why?
+
+CivMC has some pretty strict rules regarding bots and mods. Mods that read ANY block information for ANY purpose other
+than an approved exception, are automatically illegal and bannable. And since ChestTracker reads the container-block
+location and type, it is thus illegal. The admins have ignored requests to grant ChestTracker (and similar mods) an
+exception. As such, the only way forward is to fork ChestTracker to make it legal.
