Where can I learn guitar for free?

Whoa! I have been interacting with lots of people of-late and have picked one question which was very common among the beginners,

 Where can I learn guitar for Free?

I want to tell, Nothing comes for free in this world, there is no free lunch.

But to start with, in my case I am learning guitar online from YOU TUBE and for FREE.

I think it is a fantastic way to learn from there. There are pros & cons. But yes, if you are willing to invest time then you can learn absolutely anything from there. I never thought I would ever do this but then gradually it became an addiction. Infact there are ways where you can save on internet also.I will just show you how:

• Initially do some homework on the channel. You may find many videos that give you information, lot of content but that may or may not interest you. 
• Find the right video.
• Download "You tube video Downloader" from google. This software comes for free, no need to upgrade initially. Later as per usage you may decide to upgrade as well.
• Copy the url of the song from youtube video and paste it in the YTD-You Tube Downloader and then click Download
• Now you have a video which you can watch anytime without internet also.
• Learn & play.
