About your profile
Your profile page tells people the story of your work through the repositories you're interested in, the contributions you've made, and the conversations you've had.
Setting your profile picture
Your profile picture helps identify you across your GitHub Enterprise instance in pull requests, comments, contributions pages, and graphs. You can choose to have a profile picture that represents you, your likeness, or your spirit animal.
