Creating pull request to correct readme files

[oddstr13]

Please do not spam open source projects with your school assignments in this way, it creates unnecessary burden for the maintainers of the project.

If you simply need to make pull-requests like this, you can do that on your own repositories; simply create a new branch on your own repository (preferably one you've made for demonstrations like this), push it to GitHub, and you should be able to create a pull-request into the main branch of your own repository.
An alternative is to submit pull-requests to your classmates repositories.

A good starting point is GitHub's Hello World tutorial: https://docs.github.com/en/get-started/quickstart/hello-world
