Creating a new organization from scratch
Create an organization to apply fine-grained access permissions to repositories.
When you create a new organization from scratch, it doesn't have any repositories associated with it. For more information on adding repositories to your organization, see "Creating a new repository" and "Transferring a repository."
在“Organizations（组织）”部分，单击 New organization（新建组织 ）。
Follow the prompts to create your organization. For more information about the plans available for your team, see "GitHub's products."
