For like, 90% of all mods, you do that, if it requires anything else then it will say so in the README. Merging mods together is far more involved but if you have to check out the merging tutorial and follow that step by step. I've personally yet to have to merge any more than one mod, and it was so small that I could just use one of minimauls tools rather than getting elbow deep in xtbl files.
