....pretty straight forward. 6 lines = 6 strings; the number is the fret you play.

----------------5 (5th fret bottom string; the one that breaks all the time)
--------------4--
-----------3----- (3rd fret bottom-mid string; the one I can never mute right)
--------2--------
-----1-----------
--0-------------- (open top string; the fat one)


Try Google, it knows everything.
