Anyways I'll give you hint, first you need to tell the FMS where it is.
Ha, lol. You're half way there now.
If you have flight sim, I suggest using an addon that has a decent FMC with it; such as PMDG or Level-D. Sure, it's just a sim, but it's got the basics and it'll help you along.
Try a search on Google for manuals or guides too.
Your question is fairly vague and very expansive and can't really be answered on a forum, but if you have any other particular questions on one specific part or procedure involving the FMS, don't be afraid to ask.
