Update ReadMe.md

[kirkster96]

The ReadMe for this repo needs some work. Here are some sections I think needs to be added to the readme:

• [ ] Short intro description
• [ ] How to use this program
• [ ] Changelog

See here for example: https://github.com/kirkster96/atomic-nearest-neighbors/blob/master/README.md

Let me know if you need some help with how to write markdown files. This website has some good documentation of what you can do in .md files.
