Th FAQ is divided into two sections:

Quick FAQ – Go here for short answers to the most common questions. Best to start here if you’re new.

In-Depth FAQ – Go here if you’re looking for longer answers to more complex questions – usually complete with diagrams and scientific jargon. This is an archive of a series of full-length posts. I try to add a new in-depth FAQ about every couple of weeks, based on questions you ask.
