title: Difference between "ionic cordova plugin add" and "npm install @ionic-native/plugin --save"
body: <p>I have been trying to use the ionic-native plugins provided by Ionic 3. When I read the install instructions, there are always 2 command lines instead of one.</p>
  
  <pre><code>ionic cordova plugin add cordova-plugin-camera
  npm install --save @ionic-native/camera
  </code></pre>
  
  <p>If my memory serves me right, only a single command similar to <code>ionic plugin add somepluginhere</code> will get the job done in the old days.</p>
  
  <p>What are the differences here?</p>
