Good news! Github has added an ability to create an informative bio for its users. They call it Profile READMEs. We can hope Developers will post some detail about themselves so that Recruiters reach out to the right people.
Adding a bio is straightforward – you need to create a repository with the same name as your username and drop a Readme.md file there. That file’s contents will be shown on your front profile page – publicly.
From Profile readmes, we can get extra info about members, including their skills and preferences, and often, public email addresses.
