Low Poly Mesh Rig Capatibility?

Hello, I’m fairly new to Blender, used tutorials to get a little progress in “human” development. I’ve managed to get a low poly shape done, but all attempts to RIG the character “base” has failed, despite the tutorials I’ve explored. Here is the base I’m trying to rig;



My goal is to fully rig this base, so I can customize this base into many low poly characters for animations, since I’m using a low-end “laptop” right now.
Any help would be appreciated please.
