💻 How to Modify

Typically, you don't need to modify the code. However, if you wish to do so, follow these steps:

1. Run yarn to install dependencies. Note that this project is a monorepo using yarn workspaces, so npm will not work
2. Start the project in development mode with yarn start

✅ Run Tests

To run the test:

1. Start the test examples with:

   yarn start:tests
   

2. In a separate console, run the end-to-end tests with:

   yarn test:cypress
