How to make a HUD for a specific gamemode ?

I created a gamemode and his HUD and I want to make the HUD only for the gamemode, how can I do this ?

The HUD is in lua/autorun/client/

Override the gamemode’s GM:HUDPaint method with your code.

I do not understand, where do I need to place GM:HUDPaint ?

In a clientside file of your gamemode. cl_init is the root file.
