Explanation file of implemented code

This is a(n):

• New algorithm
• Update to an existing algorithm
• Error
• Proposal to the Repository

Details:

We can make a file may be READ.md file in every algorithm. reading code without explanation is difficult for learners so I am proposing an explanation of implemented programs using gifs, text, or any pictorial method. Reading merely code doesn't help much but explanation does help. I would like to work on it.
