AOE2 HD: Modding help?

Here comes nothing i guess. I'm pretty deep into the Advanced Genie Editor and Turtle Pack for modding.

I just want to simply change a unit "graphics" to something else. So, replacing new animation frames with my sprite. My second problem is that i have created a mod folder into the aoe2hd folder with all the subfolders directing to the textures, sounds, terrain etc. But somehow when i start it up, and enable it in the workshop tab. It still wont show the new mod.

I just want to replace existing units with new graphics. Any idea how?
