By finishing this chapter, you should be ready to fill in the details to build a public profile that is viewable by anyone interested to know more about you. Your account is yours and yours only, so it should be secured as much as possible. By now, you should have followed the steps to secure it with 2FA and be a little bit safer.
You have also learned how to configure repository's settings regarding its default branch and enabling or disabling features such as the issue tracker and the wiki. Another thing to remember is how to add collaborators to your project and how to transfer its ownership if needed.
These were the most important settings to consider, both user and project-related, and you should feel a little bit wiser towards the end.
