+## Adding modules
+shadPS4 can load some modules in:
+* `LLE mode`: Low Level Emulation; Understand emulation as close to reality as possible.
+* `HLE mode`: High Level Emulation.
+
+For some of the modules, it is necessary to process them in **LLE**. For others, they can be replaced by these supported modules and must be placed under `user/sys_modules` folder. Tested FW modules are from **11.00**.
+
