I have a painted UV map. How to use it on my model?

I made a custom UV map, how might I use it on my model?
I made a UV map in Blender and exported it but it was blank. So I went ahead and painted it in. Now I am done and I just want to know how to place it back into Blender to be used on my model?

Add a material
Add a image texture to the material
Select your image
Set the mapping to UV
Set the influence to Color


Thank you very much sir. Marking as solved.

WAIT WAIT: I have an additional question, If I make a UV map for an object. And then I cut away part of the object. Can I still apply the UV map and have it work covering the remaining part of the object?
