+
+## License file management
+
+To download your Grafana Enterprise license log in to your [Grafana.com](https://grafana.com) account and go to your **Org
+Profile**. In the side menu there is a section for Grafana Enterprise licenses. At the bottom of the license
+details page there is **Download Token** link that will download the *license.jwt* file containing your license.
+
+Place the *license.jwt* file in Grafana's data folder. This is usually located at `/var/lib/grafana/data` on linux systems.
+
+You can also configure a custom location for the license file via the ini setting:
+
+```bash
+[enterprise]
+license_path = /company/secrets/license.jwt
+```
+
+This setting can also be set via ENV variable which is useful if you're running Grafana via docker and have a custom
+volume where you have placed the license file. In this case set the ENV variable `GF_ENTERPRISE_LICENSE_PATH` to point
+to the location of your license file.
