 ### Create and access the ReactI13n instance
 
 What we do with `setupI13n` is that we will create the `ReactI13n` instance, along with a root node of the I13nTree, passing them via component context to the children. 
 
-It's designed to work within React components, you should be able to just [utilFuctions](https://github.com/yahoo/react-i13n/blob/master/docs/guides/utilFunctions.md) and trigger i13n events. In case you want to do this out of React components, you can access `window._reactI13nInstance` directly.

-If you have multiple react trees in one page, we will create multiple i13n trees based on how many react tree you have. On client side the [utilFuctions](https://github.com/yahoo/react-i13n/blob/master/docs/guides/utilFunctions.md) still work based on the global instance object, while on server side, only the children under `setupI13n` can get the react i13n instance as we don't have a proper way to share the reactI13n instance without causing [memory leak](https://github.com/yahoo/react-i13n/pull/100).
