You shoud really download the source Tarbal of Samba for the documentation, if nothing else.
Installation instructions are very clear and detailed.
Note: Your smbd and nmbd executables will be somewhere else if you've installed from package.
Also, in Slackware, you have to comment out the entries for smbd and nmbd from the /etc/inetd.conf, unless, of course, you want to start Samba from inetd. Again, refer to the Samba docs.
