Custom Animation. FOR THE FINAL TIME!

Hi everyone I have trawled and scraped my face along the rough stone floor of the internet looking for lovely tutorials on getting custom animations into Gmod, but in the process had to piece together dirty hacks of information which has lead me to hitting my head against yet another brick and wood wall.

I’m really sorry if this is the wrong place to post this thread, but I recon you Lua guys are the best people for this kind of question.

So for the last time HOW DO YOU GET CUSTOM ANIMATIONS INTO GMOD (and I dont mean some toolgun animation bs).
e.g. henties, swim anim
