 You can save and load scenes with a 3DStreet Cloud account. So that you don't have to create a new password, and so that we don't have to store it, we use a third-party provider Google Sign-in for account access.
 
-## Beta software
-
-3DStreet is "[beta](https://en.wikipedia.org/wiki/Software_release_life_cycle#Beta) software" in active development and may not behave as expected. As we continue improving the product, we do our best ensure backward compatibility so that your 3DStreet data remains useable, but you may experience data loss. In using these features, you understand that you use this application at your own risk including your acceptance of the liability of potential data loss per the terms of the [License](https://github.com/3DStreet/3dstreet/blob/main/LICENSE) that we use to make 3DStreet available to you.

 ## File export options
 In addition to saving and sharing files with 3DStreet Cloud, you can instantly export your 3DStreet scene as a downloadable file in your browser.
 
 * Editable 3DStreet JSON Files - You can save and load scenes using 3DStreet JSON files ending in `.3dstreet.json` extension. These files contain layers, entities and components that make up your street scene in JavaScript notation. This is the same JSON format used in 3DStreet Cloud but made available as a file that you can save and store locally. Usually you can continue editing a 3DStreet JSON file after reloading it in a future session.
 * Read-only glTF Scene Files - You can also export scenes in the glTF graphics transmission files ending in `.glb` extension. These files can be used by other 3D applications such as Blender, Unreal or Unity. This is a binary file and is not editable again by 3DStreet Editor in future sessions.

-2) In the Layers left panel select the new "Intersection 90º" layer you created
-3) Open the right-hand panel and scroll down to "Intersection" and click the down arrow
-

-
-| Property | Description | Default Value |
-| --------- | --------- | --------- |
-| dimensions | Specifies the width and depth of the intersection. First value represents width, second value represents depth. | '20 20' |
-| sidewalk | Sets the width of the sidewalk at each side of the intersection. Values are set in the order of west, east, north, south. |  '0 0 0 0' |

 ## SVG Extrusion Component
 
-3DStreet SVG import is designed to accept 1 closed path or geometry at a time in a simple SVG format. This component accepts a `svgString` and creates a new entity with geometry extruded from the svg and applies the default mixin material grass. Extrusion can help to emulate the look of curbs and other surfaces. This method requires separates SVG imports for different parts of a scene.
-
-## Add an image
-
-This code snippet creates a plane geometry with a user specified image path. 
-
-Replace the https://... part to a publicly accessible HTTPS URL pointing to your image. We recommend [glitch.com](https://glitch.com/) as a great web host for assets like this but any host that provides a public URL path is fine.
