 Code style
 ~~~~~~~~~~
 
-The code-style for matrix-js-sdk is not formally documented, but contributors
-are encouraged to read the code style document for matrix-react-sdk
+The js-sdk aims to target TypeScript/ES6. All new files should be written in
+TypeScript and existing files should use ES6 principles where possible.
+
+Members should not be exported as a default export in general - it causes problems
+with the architecture of the SDK (index file becomes less clear) and could
+introduce naming problems (as default exports get aliased upon import). In
+general, avoid using `export default`.
+
+The remaining code-style for matrix-js-sdk is not formally documented, but
+contributors are encouraged to read the code style document for matrix-react-sdk
 (`<https://github.com/matrix-org/matrix-react-sdk/blob/master/code_style.md>`_)
 and follow the principles set out there.
