Success! Created react-etherjs at C:\Users\miyazato\work\ethereum\react-etherjs Inside that directory, you can run several commands:

npm start
  Starts the development server.

npm run build
  Bundles the app into static files for production.

npm test
  Starts the test runner.

npm run eject
  Removes this tool and copies build dependencies, configuration files
  and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

cd react-etherjs
npm start

Happy hacking!

cd react-etherjs
