HI,

If you are new to github, you can start by creating a new github account and then create a repository. Initially if you dont want to go through the commands and all, you can do the things from the github UI itself.

* create an account in github: https://github.com/
* create a repository: https://docs.github.com/en/repositories/creating-and-managing-repositories/creating-a-new-repository

* add files to git repository from UI:   https://docs.github.com/en/repositories/working-with-files/managing-files/adding-a-file-to-a-repository

If you need to learn commands, you can try to understand the basic commands like pull, push, fetch, commit etc.

See this video explaining the same: Creating GitHub Repository and Introduction to Git Commands

Thanks
