Custom Playermodel Animations

My buddy asked me to make him a custom playermodel with a custom running animation. I managed to get the playermodel in Gmod albiet without any animations at all. I’m not quite sure where to go from here as I couldn’t find any guides that specifically help with using custom animations for running or walking and such, any help would be appreciated.

Here’s the ragdoll I used as a playermodel that has the custom animations in the files: Steam Workshop::Armless Model FOTT
