How do i install Viro react correctly on windows 10?

Question

I tried a few options.
Option 1 (site):

npm install -g react-native-cli react-viro-cli
react-viro init test_app
npm start

Error!

    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
 },

Option 2 (site):

react-native init test_app --version=0.59.3
cd test_app && npm install -S -E react-viro
npm start
// Running port 8081.
// What's the next step? Ok, i installed ngrok
ngrok http 80 

I don't know what to do next. Please give a detailed installation plan to the completed sample on android.
