FAQ/How to Section Suggestions

Well i got your feedback on my idea and i really think this would be a good thing to have. But i would now like to try and get some things going that would go into it. Only post suggestions in here please. I know this is in off topic but id like to keep it organized. And with each suggestion, if you have the answer/methodology for the question or how to please post that as well (ex. how to install guages, please post your how to on it so that it can be used in the section)
