Adjusting Rear Derailleur

Many of us cyclist face problems when our rear derailleur (rd) don't work properly. Adjusting it can be a frustrating job. I'm frustrated when my rd does not work properly. The cause could be a lose cable, being hit by a rock, etc.

Below are the 2 links you can read about how to adjust a rd in the following links:

However, I prefer to watch it on video as it is much clearer and easier to understand. 

Below are the youtube links that I've watched, applied what I saw on my own bike and it is works.

The first video is a simple adjustment whereas the second is advance adjustment.
