See the included INSTALL file for building instructions. To verify the signatures:

gpg --keyserver pgp.mit.edu --recv-keys '7EE6 5E30 82A5 FB06 AC7C 368D 00CC B587 DDBE F0E1'

You shouldn’t really trust this key without verifying its fingerprint. See it with gpg --fingerprint staff@irssi.org and ask someone if it matches (eg. on #irssi).
