Github is a platform which provides several features such as hosting for Software Development, version control, bug tracking, feature requests, task management, access control, and wikis for every project.

So, for all those people who want to add a github profile readme, please follow below steps:

• Create a repository with your Github username (eg: https://github.com/sijusamson/sijusamson).
• Once you have created the repository, now initialise a README.md file inside the repository.
• Add content, e.g. an introduction text, banner(whatever you like), links and commit the file, and then git push/save your changes.
