+# Babel
+
+storybook looks for a root `.babelrc` in the project for its babel config. However, we are using `.babelrc.js` which is not supported. Rather than putting effort into this we are just having a custom `.babelrc` in this folder which is the same as `.babelrc.js`. This is lame, but we are looking to move away from storybook in the short term anyway.
