better directions

[onewiseburdman]

please write some better directions-I am not sure what I am supposed to install via NPM.

Am I supposed to install summernote via NPM? I guess I am missing something.

The reason I say that-I am getting this error:

summer-note.js:59 Uncaught TypeError: Cannot set property 'onChange' of undefined

I had to make a change also to the controller, to this.set:

onContentChange(text) {
this.set('postContent', text);
},

  changeHeight(someObject) {
    let height = someObject.doSomeCalculationToGetHeight();
    this.set('contentHeight', height);
  },

Ember was complaining about it. It's just a new ember install running ember 2.17.1
