The screens you went through in the recipe are Creating a repository at GitHub server. In essence, it is simply creating a directory and running git init.
Adding the extra files (.gitignore, LICENSE, and README.md) is fairly simple too. Setting up a good .gitignore takes time, but you get a good starting point with the generated one.
GitHub also sets up access control for your repository. Only members of the organization have write permissions; that is, they have the rights to commit. In the settings of the repository, you can define more precise access control under the menu item Collaborators & teams. A team is a group of GitHub users who work together. In your company, you might have iOS, Android, and DevOps teams.
