# Installing an add-on
{% hint style="info" %}
Non-admin users cannot access the catalog, install wizard, or detail view for add-ons.
{% endhint %}
To install an add-on, navigate to **Add-ons** under Administration in the menu and click **Install** on the application you would like to install.
Add-on configuration varies by application. Refer to that application's documentation, linked in the [add-ons catalog](/sts/admin/add-ons.md#add-ons-catalog), for help with installation.
#### Configuration
| Field/Option | Overview |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Chart source | A read-only field that shows the OCI Helm chart reference used to install this add-on. |
| Version | Select which chart version to install. The most recent version is marked "(latest)" and selected by default. |
| Add-on configuration |
Appears once a version is selected. Contains the connection and configuration fields defined by the chart's values. The fields vary between add-ons - each one is generated from the chart's own schema.
Fields whose name includes key, token, secret, or password are masked by default - click the eye icon to reveal them.
|
Click **Next** when you have completed the initial configuration.
#### Assign teams
| Field/Option | Overview |
| ----------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Teams | Optionally select which Portainer teams can access this add-on. You can also type a new team name here to create one. |
| Deny access to Portainer for the selected teams | When enabled, members of the selected teams are redirected directly into the add-on and cannot access the main Portainer UI. This makes the add-on their primary interface. |
Once you have complete both steps and click **Finish** to deploy the Helm release.
