W3 Not Running

Hello. I have recently begun experimenting with W3. The compile seems to 
work perfectly, though I am having a problem.
After compiling, I ran 'make install' and found the package in 
/usr/local/share/emacs/site-lisp. My next question is, how do I run it? 
Can I simply type in the path and name after M-x? Because, if so, I've 
tried that and it didn't work. :)
Also, I would like to appologize if this question has been asked before. 
I am still rather new to emacs.
