Changing header - phpBB 3.01

[kachano]

Hi,

I've been trying to change the overall header (phpbb logo included) for a week now but can't figure it out.

Can anybody please help me out with this. I want to replace phpbb logo with our own and design the "forum name" myself.

How do I go about it?

I thank you in advance for you help.
