I mean, unless you're not computer literate at all, there are numerous threads on what impulse responses are, what amp simulations to use, which ones are free, where to get them, how to dial in a tone, etc.
Here's a custom intra-forum Google search function:

Literally just google "how to make metal tone POD Farm" and you'll get hundreds of hits, both here and on normal Google.
To the contrary re: your previous post, I've found that people here are, to a bewildering degree, willing to answer the same 5 questions about guitar tones, how to use impulses, etc. over and over and over again with no real rudeness whatsoever, and each time somebody says something new and interesting. I knew absolutely nothing about any of this when I registered here, and I've just learned through osmosis how to make mixes that don't sound like complete turds. The first thing I learned was what to do with my guitars, by reading old threads.
You're not going to sound like Will Putney after 5 hours of research, but you should also get the answers you're looking for if you use the forum search function and Google, and then look on YouTube for whatever knowledge gaps you may have. If, at that point, you've spent hours looking and still don't understand, then that's when I post a thread here, or if it's something specific enough that it probably hasn't been answered before. But this thread is kind of like writing a letter to the editor in Better Homes and Gardens asking, "HELP ME HOW DO I ACHIEVE BETTER HOMES AND GARDENS," so that's why some of the responses are kind of snippy.
