+# Technical information about browser support
+
+[codethemicrobit.com][] requires that you use a recent version of a modern
+browser, such as Microsoft Edge, Google Chrome, Mozilla Firefox, Safari, Opera,
+or IE11.  This is because the editor uses modern web technologies such as [web
+workers][] to enable compiling [TypeScript][] in the browser, or the using the
+same [Monaco][] editor that powers [Visual Studio Code][].
+
+[codethemicrobit.com]: https://codethemicrobit.com
+[web workers]: http://www.w3.org/TR/workers/
+[typescript]: http://www.typescriptlang.org
+[monaco]: https://microsoft.github.io/monaco-editor/
+[visual studio code]: http://code.visualstudio.com
+
+Most modern browsers automatically update themselves, but in some environments
+such as schools these automatic updates are disabled for security. **We
+strongly recommend that you use the most recent version of any of these
+browsers**, but if you can't then you must use at least:
+
+| Browser           | Minimum version | Release date   | Windows     | Mac        |
+| ----------------- | --------------- | -------------- | ----------- | ---------- |
+| Edge              | 12              | March 2015     | Windows 10+ | N/A        |
+| Internet Explorer | 11              | October 2013   | Windows 7+  | N/A        |
+| Mozilla Firefox   | 31 ESR          | July 2014      | Windows XP+ | OS X 10.6+ |
+| Google Chrome     | 38              | October 2014   | Windows XP+ | OS X 10.6+ |
+| Safari            | 9               | September 2015 | N/A         | OS X 10.9+ |
+| Opera             | 21              | May 2014       | Windows 7+  | OS X 10.9+ |
