Background

Develop an application that uses Github REST APIs to achieve the following features:

1. Search for a user profile on Github and display his account details, including, but not limited to, image, bio, username and number of repositories.
2. Have the ability to display the user followers, and following lists. (the accounts that the user is following, and the accounts that are followed by the selected user)
3. Display a detail page of the user's repositories and display the repository details, including, but not limited to, name, stars and description.
4. This information should be saved in the database for offline use
