+A `create-react-app` example is available at [./examples/cra](./examples/cra). If running `yarn install` locally in the example directory, be sure to run it with `yarn install --force --check-files` so that it pulls in the runtime (specified as a `file:` dependency).
 
-```sh
-> yarn build
-> cd examples/cra && yarn start
-# visit http://localhost:3000
-# login to https://play.dhis2.org/dev to allow the example to retrieve data
