-The build is minified and the filenames include the hashes.
-Your app is ready to be deployed!
+There is a GitHub action set up on this repository to build the React app, run tests and deploy to the GitHub Pages site on every merge to the `master` branch.
 
-See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) in the Create React App documentation for more information.
+Also when a pull request is created or updated, the GitHub action will build the React app and run tests. If the build or tests fail, the pull request will be blocked from merging until they are resolved.
