-### Setting inference
+### Using GitHubBox.com
+An easy way to import a repo to CodeSandbox via URL is with GitHubBox.com. Append 
+'box' to your github.com URL in between 'hub' and '.com' and it will redirect to 
+CodeSandbox.
+
+Here's an example:
+
+Change the GitHub URL:
+[https://github.com/reduxjs/redux/tree/master/examples/todomvc](https://github.com/reduxjs/redux/tree/master/examples/todomvc).
+
+To:
+[https://githubbox.com/reactjs/redux/tree/master/examples/todomvc](https://githubbox.com/reactjs/redux/tree/master/examples/todomvc).
+
+The result is we take the last part of the url (everything after github.com) and 
+use it in our importer at codesandbox.io/s/github/, adding the repo to CodeSandbox.

+### Using a Browser Extension
+We have browswer extensions for [Chrome](https://chrome.google.com/webstore/detail/open-in-codesandbox/hdidglkcgdolpoijdckmafdnddjoglia) and [Firefox](https://addons.mozilla.org/en-GB/firefox/addon/codesandbox/), which add an 'Open in CodeSandbox' button to GitHub repo pages. This makes it easy to import existing projects from GitHub in to CodeSandbox.
