  <p>I've Installed the package and linked it as mentioned in the project's GitHub page 
  <a href="https://github.com/rt2zz/react-native-contacts" rel="nofollow noreferrer">https://github.com/rt2zz/react-native-contacts</a></p>
  
  <p>I've also added the permissions to the android-manifest file.
  How do I get it works</p>
