Please don't use links as answers.

The user's question is not easily summarized and requires a fairly lengthy response to answer comprehensively. I am not going to write several page tutorial which others have already written, and written well. Since the OP said they'd already googled and couldn't find an answer, I think providing a link to a post that they missed is entirely acceptable.
