 # Scene Studio
 
-Navigating to `/studio` will show you the projects page, where you can open existing projects or create a new one.

-The scene consists of a list of 'components' which are the various features, templates & prefabs. These are what you would normally expect in a scene studio, such as models, colliders and audio, but a wide range of integrations are supported such as portals to let you traverse between worlds.

 # Locations & Instances
 
-Locations can be thought of as instantiations of scene. This is how you connect your scene to a shared session.
-
-Locations can be loaded via the `/location/<locationName>` route, where `locationName` is the name of the location. By default, the locations `default`, `apartment` and `sky-station` are added.
+**Locations** can be thought of as instantiations of a scene.  
+They allow scenes to be connected to a session that can be shared between multiple devices at the same time.
 
 An **instance** is an individual session running at a location, in which users are connected together in real time. This allows the deployment to scale events and locations to potentially millions of concurrent users without having to support them all on a single instance. 
 
-There are two types of instances: **world** instances and **media** instances. World instances handle the spatial objects in the scene, such as avatars, vehicles and grabbables. Media instances handle realtime audio, video and screenshare.
