You can create a new organization by either setting up a new organization or converting an existing personal account into an organization.
Organizations are shared accounts where businesses and open-source projects can collaborate across many projects at once. Owners and administrators can manage member access to the organization's data and projects with sophisticated security and administrative features.
Create an organization to apply fine-grained access permissions to repositories.
You can convert your user account into an organization. This allows more granular permissions for repositories that belong to the organization.
After you create an organization, you should give Owner permissions to a small group of people who will manage the organization account.
You can make anyone a member of your organization using their GitHub Enterprise username or email address.
If a member of your organization no longer requires access to any repositories owned by the organization, you can remove them from the organization.
