+# Power off simulation
+
+This module simulates power off callbacks, equivalent to the `POWEROFF` module on DTL-T.  
+This is useful for situations when debugging on systems that do not support
+power off callbacks, such as SCPH-10000.
+
+## Configurations
+
+There are multiple configurations of this library, allowing the choice of
+balancing between size, speed, and features.
+
+*   `poffsim` -> The recommended version.
+
+## How to use this module in your program
+
+In order to use this module in your program, use `LoadModule` or \
+`LoadModuleBuffer` with no arguments.
