 **Yarn Linking**
 The best way to develop locally and test is to link the individual package you’re working on and run lerna in watch mode.

 Passing unit tests are only necessary if you’re looking to contribute a pull request. If you’re just playing locally, you don’t need them. However, if you’re contributing a pull request for anything other than making a change to the documentation, fixing a formatting issue in the code (i.e., white space, missing semi-colons) or another task that does not impact the functionality of the code, you will need to validate your proposed changes with passing unit tests.
 
-**Using the setup-dev:react-native script to work with React-Native apps**
-
-> Note: All the below commands to be run from the local amplify-js library root
-
-To develop locally alongside a React-Native app, make sure to,
-
-1. Finish the build steps mentioned in the section: `Setting up for local development` to set up your local `amplify-js` repository for development.
-
-   > Note: To set up a sample React-Native app -- configure your [development environment](https://reactnative.dev/docs/environment-setup) and [create an app](https://reactnative.dev/docs/environment-setup#creating-a-new-application). Note the path to the app as it is required in the next step.
-
-2. Run the below command in the root of the amplify-js local repository with a package name (auth for example):
-   > Make sure to have [watchman](https://facebook.github.io/watchman/docs/install.html) installed before running the command below
-
-```
-npm run setup-dev:react-native -- --packages @aws-amplify/auth --target ~/path/to/your/rn/app/root
-```
-
-> Note: This script runs a continuous job in the newly opened tabs to watch, build and copy the changes unlike the usual linking method.
-
-The options `--packages` is used to specify single or multiple package names and the `--target` option is used to specify the path to your sample React-Native app.
-Optionally, you can use the shorthands flags `-p` and `-t` for packages and target path respectively.
-
-> All scoped packages must be prefixed by `@aws-amplify/` . For example: `@aws-amplify/auth`
-
-To develop multiple/all packages, provide the package names separated by a comma or the flag `--all` or `-a`:
-
-```
-npm run setup-dev:react-native -- --packages @aws-amplify/auth --target ~/path/to/your/rn/app/root
-npm run setup-dev:react-native -- --all --target ~/path/to/your/rn/app/root
-```
-
-> Note: `--` right after the script name is important to provide the flags with their values.
-
-**Debugging problems with the `setup-dev:react-native` script**
-
-- If the WML command does not do anything after adding the links, watch its src file using watchman. Run the below from the root of this repository:
-
-  ```
-  watchman watch node_modules/wml/src
-  ```
-
-- When using VScode, for the script to open a new terminal and tabs you will need to provide the editor accessiblity permissions.
