# License Management

### License Installation & Updates

To ensure your system runs without interruption, you must upload a valid license file provided by **programmfabrik**.

* In the **Configuration Base** locate the **License Management** section
* The license must be a valid **.json** file. 
* Locate the license upload section and select the file provided to you.

For more information on licenses, please refer to [fylr Licenses](https://docs.fylr.io/license-management).

### Expiration Warnings & Notifications

The licensing system includes an automated warning service to prevent disruption to your fylr instance.

#### Automatic Emails

Warnings are sent via email at the following intervals before the license expires:

* **30 Days**
