-## Changing permission level
-
-Every user in the organization can be promoted from the [Member permission 
-level](https://docs.semaphoreci.com/account-management/permission-levels/#members) to the [Admin permission level](https://docs.semaphoreci.com/account-management/permission-levels/#admin). This can be done by following these steps:
-
-1. Go to the **People** page of your organization
-2. Click on the **Promote** button next to the username of the user you’d like to promote
-
-The same steps should be followed if you want to change a user's permission level from 
-Admin to Member. In this case, click on the **Demote** button next to the username.
-
-Only an Admin or the Owner of the organization can perform these steps.
-
-**Note:** An organization can only have one [Owner](https://docs.semaphoreci.com/account-management/permission-levels/#owner). If you’d like to transfer ownership, please visit [this page](https://docs.semaphoreci.com/account-management/organizations/#transferring-ownership-of-an-organization).
