+
+To run a dev server with a sample UI, run
+`npm i` and then `npm start`
+
+The sample UI takes configuration info from the URL params. Visit http://localhost:3000/?subscription-endpoint=wss://thankful-beetle-75.hasura.app/v1/graphql&endpoint=https://thankful-beetle-75.hasura.app/v1/graphql&header=x-hasura-admin-secret:q3qsst5kj9xwYg7nvJw73uX0TgvSObwcNqjj0vcGaB89AX5pxvsFshvgxidV5l9j to get sample data populated.
+
+To run tests, run
+`yarn cypress open-ct`
+
+To build a package for publishing to NPM, run
+`npm run build`
+
+This will create a 'dist' folder which can be published to NPM using `npm publish` flow.
