Look around and use the “Search” function, it is very helpful if you’re looking for some specific information. If you don’t find what you want the first time, try different “key words”.
A good place to start is here, the “Rules & Stickies” section, pay special attention to the “Stickies”: Rules & Stickies
If you’re looking for information on how to build a laser check out the links in my sig.
