# Admin

Control who can access and change Cassis, and maintain organization-wide integrations.

Before creating a production project, [choose whether its ontology will be app-managed or git-managed](/start/choose/).

-   [Projects](/setup/projects/): What a project binds together, who can create one, and what is organization-wide.
-   [Members and roles](/setup/members/): Invite people, assign a role, and suspend or reactivate access.
-   [Domain permissions](/setup/permissions/): Restrict who edits which part of the ontology, through groups and domain grants.
-   [API keys](/setup/api-keys/): For the CLI, CI, and non-interactive agents. Interactive clients use OAuth.
-   [Install Slack](/setup/slack/): One install per organization, then map each channel to a project.
