[Asterisk-Users] Newbie questions

[Hitete]

Hi all,

I'm new to this list. very excited about Asterisk. I'd like to find good
docs about it.
Can you advise me on docs ?.Or even books ?.
If I only want to use asterisk in order for my friends and family to call
each other by passing through my pbx (without going in the usual telephone
system) I can right ?.

All I need in that case is a PC right ?. No Xtra hardware needed ?.
