Guide for beginners

[huntrashmi]

I'm a beginner.

I need:
RoundCube working on boot
No server stuff (IMAP, POP3) (I have that already externally)
Just basic config that I can log into with my external web email
I'm not sure how to set it up, and I don't know how to configure the databases nescessary.

Any advice on how to start?
