+### Testing the SDK Locally

+Please be sure to build your repo before proceeding any further.
+In order to manually test your SDK changes locally, you must use [yarn link](https://classic.yarnpkg.com/en/docs/cli/link):
+
+```shell
+$ cd packages/firebase
+$ yarn link # initialize the linking to the other folder
+$ cd ../<my-test-app-dir> # cd into your personal project directory
+$ yarn link firebase # tell yarn to use the locally built firebase SDK instead
