I need help on starting up

Guys, I found SETI very interesting and just made an account, then joined the team AboveTopSecret.com, but now I wonder what should I do next, because the BOINC Manager is very confusing, I tried to google for any instruction but as far as I saw, they did not help much. So can any of you tell me what I should do or just post me a link to somewhere that can help me get started? I will be grateful for the helps.
