 Code coverage reports are currently available only for the `@rjsf/core` package. They are generated using [nyc](https://github.com/istanbuljs/nyc) each time the `npm test-coverage` script is run.
 The full report can be seen by opening `./coverage/lcov-report/index.html`.
 
-### Notes on the local playground
-
-The playground located in `packages/playground` contains code that is published as the `@rjsf/playground` package. This package is used by the local playgrounds in packages such as `packages/core`, so that when you run `npm start` from `packages/core`, it will run the playground component from `@rjsf/playground` but with the local changes to react-jsonschema-form.
-
-Note that when doing local development in a package such as `packages/core`, making changes to `packages/playground` will not affect the local playground that is run from `packages/core`. This should be fine in most cases for development, unless you need to update and test the default playground examples. In this case, you could use `npm link` to use the latest changes both from the playground and your package. As an example, to do this when developing locally on `packages/core`, you can run:
-
-```bash
-cd packages/playground
-npm run build:lib
-npm link
-cd ../core
-npm link @rjsf/playground
-npm start
-```
-
-After the above is run, you will have a playground that has both your local changes to `packages/core` and `packages/playground`. Note that while the `packages/core` changes will live reload, the `packages/playground` changes will not -- you will need to run `npm run build:lib` from `packages/playground` each time you update a playground example.
