title: Adding Intellisense in VSCode
body: <p>I checked several post before asking but didn't find a simple answer.
  I am adding a new language extension in VSCode. This language is a proprietary which is quite basic.
  Colorization and snippets are done already.
  But now I am stuck with intellisense.</p>
  
  <p>I did it already for Sublime and it was pretty simple: add a file mylanguage.sublime-completions
  I didn't find the equivalent with VSCode.</p>
  
  <p>Is it an easy way?
  I saw some answers related to Typings and installed on VSCode the extension Typing Installer but I dont know how to use it.
  I installed Typings also by doing this: npm install -g typings
  but again i don't know how to use it :(</p>
  
  <p>Would be glad if somebody could unstuck me !</p>
