 ## Base Concept
 
-With CodeSandbox you can import any GitHub repository as a sandbox, this concept is described in more detail [here](/docs/importing#import-from-github). An imported sandbox will automatically stay in sync with the GitHub repository; if you make a commit to GitHub it will reflect immediately in the sandbox.

 For that reason we've made GitHub sandboxes immutable, this means that you cannot make direct changes to the sandbox itself. However, you can still fork the sandbox. When you create a fork of a GitHub sandbox we will still keep a reference to the original GitHub repository. This allows you to create commits and open pull requests from the forked sandboxes.
