Please see the playground environment for resources. To start a playground environment run in your terminal `yarn dev` This will run Next JS environment on localhost:3000 for building the element, and also run a watch script on the library.

No need to be overly concerned about the css because a figma design hasn't been made yet.

An example of each component can be found [here](https://github.com/radix-ui/design-system/tree/master/components)
copy and pasting from here is acceptable, because the focus is to get more structure in place and also for contributors to get more familiar with the project and tech stack.
