 Once the installation is done, Sofie should be running on [http://localhost:3000](http://localhost:3000). Next, you need to make sure that the Playout Gateway and Ingest Gateway are connected to the default Studio that has been automatically created. Open the Sofie User Interface with [Configuration Access level](../features/access-levels#browser-based) by opening [http://localhost:3000/?admin=1](http://localhost:3000/?admin=1) in your Web Browser and navigate to _Settings_ 🡒 _Studios_ 🡒 _Default Studio_ 🡒 _Peripheral Devices_. In the _Parent Devices_ section, create a new Device using the **+** button, rename the device to _Playout Gateway_ and select _Playout gateway_ from the _Peripheral Device_ drop down menu. Repeat this process for your _Ingest Gateway_ or _Sofie Rundown Editor_.
