Raid help?

[Dakalebii]

I've been playing BnS for a few years now (before NA), but I still have yet to touch on raids.
I want to learn how to do them properly, but don't know where to start. I do not want to go into raids blindly, as I do not want anyone to get mad at me. I just want to do them for fun and upgrading gear.
If anyone can help me go through a raid and teach me the mechs, that'd be wonderful. :) Please keep in mind I don't know very many abbreviations in the game, as I have only been a casual player, but want to get more involved.
Any help is appreciated, thank you.
