Requirement to import starter kit
Highly recommend to go though the installation ref from official expo site and install Expo XDE.
Once finish those installation, you can start import the starter-kit to Expo and start development.
Click Open existing project to import the project, then you can open this project on your mobile phone via Expo client.
Select your familiar editor, like Atom, VSCode or Sublime Text, to open the the project, and start coding.
