GitHub: how do I make a user an admin of an organization?

I need to transfer a repository from a user account to an organization the user is a member of. Per GitHUb's docs, I need to make the user account an admin of the organization first.

GitHub's docs describe the different levels of access to an organization, but I can't find out how to actually change a user's level of access to an organisation.

How can I make the organization member an admin?

Access levels in GitHub are configured per Team inside the Organization.

1. Log into GitHub.

2. Switch your account context to the organization using the dropdown near the top-left of the screen:

   

3. Click on "View organization":

   

4. Click the Teams tab in the top navigation bar:

   

5. Decide whether you want to change the permissions of an existing team (and all of its members) or to create a new team for a single user.

   • If you are modifying an existing Team,

     1. click on the Team name,

     2. then click the gear icon at the top right,

     3. then change the Team's access to Admin and

     4. click Update.

   • If you are creating a new Team,

     1. click the New Team button,

     2. give the Team an appropriate name,

     3. set its access to Admin and

     4. click Create Team.
