 ## CodeSandbox Integration
 
 This SDK uses the API token from your workspace in CodeSandbox to authenticate and create sandboxes. Because of this, the sandboxes will be created inside your workspace, and the resources will be billed to your workspace.
 
-You could, for example, create a private template in your workspace that has all the dependencies you need (even running servers), and then use that template to fork sandboxes from. This way, you can control the environment that the sandboxes run in.
