+# Heap library
+
+This module provides functions related to heap management.  
+
+## Configurations
+
+There are multiple configurations of this library, allowing the choice of
+balancing between size, speed, and features.
+
+*   `heaplib` -> The recommended version.
+
+## How to use this module in your program
+
+In order to use this module in your program, you must integrate the module into
+an IOPRP image, then load the image with `UDNL`.\
+Using `LoadModule` or `LoadModuleBuffer` directly will not work, because the
+module is already loaded at IOP boot.
