need help adding models and textures PLEASE!!!!!

How do you add textures and models to ep2 hammer in sdk??? PLZ!!!

Yes, you can call me a beginner.

I always follow instructions, for instance when there were these cool cod4 textures it said to put in materials i did and it never showed up. Somebody said that for props and models so i did for hl2DM and it replaced all the textures with weird prop textures!!! HOW DO I DO IT CORRECTLY??!!!

Open up the mapping section, go to the sticky, post in there, receive similar answer to:
You have to open the .vmt file in notepad or something, then you have to see the path its in. i.e. if you see a parameter saying

$basetexture "custom/wall"

Then you put the textures inside of materials\custom\wall\ folder
