How to make contribution to GitHub correctly?

If you have a GitHub account, then you will be able to see a section called Public contributions on your profile page. Your contribution status for the past year will be showed on this section, it's called contribution calendar.

This calendar has 7 rows and 53 columns. Each cell on the grid represents your contribution status for one day, if the contribution is different, the cell color will be different. There are 5 colors in total : white, yellow, light green,green and deep green.

With this, some people start to show their creativity, they start to draw on this grid. Let's check some interesting drawings here.
