Hi Hyrdro ... welcome to Chordie
I'll try to make this as simple as possible so you can understand it ... this is what the lines represent (which are the strings) from the high "e" string to the low "E" string
------------------------ e)----------------------
------------------------ B)----------------------
------------------------ G)---------------------
------------------------ = D)---------------------
------------------------ A)----------------------
------------------------ E)----------------------
Numbers on the lines (strings) represent what Fret you're playing:
-------2--------------- e)---------2----------- (2nd Fret)
-------3--------------- B)---------3----------- (3rd Fret)
-------2--------------- G)---------2----------- (2nd Fret)
------------------------ = D)----------------------
------------------------ A)----------------------
------------------------ E)----------------------

-----2-------
-----2--------
-----0-------- "0" is an open string being played
--------------
--------------
--------------
-----2--------
-----2--------
-----X-------- "X" is a muted string
Numbers together like above mean the strings are played all at once ... when they are staggered like below, they are played individually:
---2---------2
------4--4----
