+# StackTracePlus Minetest mod
+
+StackTracePlus is a Lua module that extends `debug.traceback` to include more
+call frame information such as local and globals, locals and parameters
+dumps.
+
+This mod merely plugs this module in and replaces `debug.traceback` with
+StackTracePlus's traceback dump routine.
+
+# Installing
+
+This repository uses git submodules.
+
+Clone this repo either recursively (`--recursive`) or as usual, but make sure
+to `git submodule update --init` afterwards; it must go into the `mods`
+directory.
+
+## Mod security
+
+This mod modifies the global `debug` table which is not accessible by normal
+mods when mod security is enabled.
+
+If you have enabled mod security (`secure.enable_security` is `true`), then you
+must whitelist this mod in `minetest.conf`'s `secure.trusted_mods` config
+entry.
+
