Back from work. Here it is.
If you are a beginner, you should find the following at least interesting. My frustration was it always got complicated and I would give up thinking perhaps there is something wrong with me or I am just a slow learner. Not so. Listen on. I am going to be brief and concise.
To Play Guitar:
1- there are 7 fundamental chords.
A B C D E F G -- learn them.
Each chord can be played as a minor -- learn them.
Each chord can be played in different ways along the fret -- don't think too much about that for now.
2 - You need to learn from the beginning how to play in the right keys. Most important. This allows you to jam with others and play leads. Essentially playing in the right key means a group of chords that work well together. Do not get caught up in the theory. It will only confuse the hell out of you. Instead just learn how to do it.
Here is how you do it:
Rule one - The 1, 4 and 5 chords are major.
The 2, 3 and 6 are minor.
And the 7th chord is diminished. (most however do not use diminished chords so forget about it for now)
Here is an example. Play in the key of lets say C.
C is the hence the root chord. You always come back to the C. It is the foundation.
The chords that work with C are the 4th and 5th - which are (remember -ABCDEFG) - F and G.
Hence to play in the key of C is playing the chords of C, F and G.
That alone is enough to Jam with others others and play leads. However you have more chords to chose from. You can chose the minor chords which are 2,3 and 6 - which means D, E and A in minor form. The diminished chord you can also use is the 7th which the B.
The end. This how you play guitar. Simply learn this. It will take about 5 minutes -- just practise this for 5 minutes. You will know now how to play in sync with others. Playing in key also allows for leads to be played. You cannot play leads if you are not in right key of chords.

Next - How to Play lead Guitar
Lead guitar is all about learning a scale that fits in the right key of chords. You can also learn this in 5 minutes. Listen on.
The most well know scales are the major, minor and blues scales. However the most popular scale that is used by all musicians all over the world - is the pentatonic minor. Hence learn this. It can be learned in a few minutes. Pentatonic means 5 -- so it means 5 notes from the minor scale which has 7 notes.
Keep this dam simple. Do not over think.
Simply learn the pentatonic minor scale. This scale can also be played in 5 different positions up the fret. Eventually learn all five -- but you only need to know 1 - 3 positions. Each position has 10 notes. So if you learn all five positions - you will have (5 x 10) = 50 notes you can play for lead guitar in each key. Actually it is not 50 but really 30 notes -- will explain later if needed.
Do not think too much here. Just do.
For example, if you are playing in the key of A -- simply play A minor pentatonic scale. The pentatonic scale is the same in every other key.
------------
The next popular scale is the blues scale. It is however almost identical to the pentatonic minor scale. Once you know pentatonic minor, you will easily pick up the blues scale. Hence stick with the pentatonic minor.
Below is a video that shows how to play the 5 positions of the pentatonic minor which I think is pretty good:

The end.
You now know how to play in the right key -- and you know pentatonic minor scales to play lead.
That is all you need. You should be up and playing before the sun sets.
