 ## Getting started
 
-The Plutus Playground is written in [PureScript](https://www.purescript.org/) and uses npm and [spago](https://github.com/purescript/spago) for managing dependencies. It talks to the [plutus-playground-server](https://github.com/input-output-hk/plutus/tree/master/plutus-playground-server) which also needs to be up and running during development. The client build also depends on purescript files that are generated by the backend service using [purescript-bridge](https://github.com/eskimor/purescript-bridge).
