Reading Tabs.......

STRINGS
The thinnest string is "e" or 1.
The one above it is "b" or 2T
hen there's "g" or 3.
Then "d" or 4."a" or 5.
And the broadest one is again "e" or 6.

FRETSyou must've noticed the thin rods on the long board thingy, they're called "frets" (and the "long board thingy" is called the "fret-board").Now you know where the tuners are,right? Joining them and the fretboard is a plastic thing, called the "upper-bridge" There'll be a fret touching it. Thats the 0 fret. As you move towards the soundbox, (the part which basically produces the sounds. Most guitars have a hole on it, so it can be identified easily), The fret number keeps increasing. (the fret after 0 is 1 and after that 2 and so on).READING TABSIn guitar tablatures (tabs) the fret to be played is denoted by it's number and the number is printed in front of the string it is being played on.The tab is like a time-bar. the notation written before is played earlier.
For example:

e------------------------------------
b------------------------------------
g------------------------------------
d------------------------------------
a-------2----------------------------
e--1---------------------------------

here you play the first fret of the 6th or the "e" string and then play the second fret on the 5th or the "b" string. That's about it.
Few tricks.
/ : slide up
\ : slide down
~ : let it ring
h: hammer ons (sounds little similar to slide up, but is sharper)
The hammer on in the first part is played by first plucking the 2 and then quickly pressing down 3 quickly.

stuff like hammer-ons, pull-offs and sliding but that comes at higher level .
