The closest you're going to get to a brain-dump on all things Fossil is the existing documentation. Read as much of that as seems relevant to your situation, then try to apply it to your use case. If, after attempting these things you find that you still have questions, you are welcome to post each here under a dedicated, focused topic.

Wide-open solicitations for information can result in little more than an ad hoc regurgitation of the documentation, which we've already poured quite a lot of effort into. Please respect that effort.
