  -In this code, we import the `init` function from the package `meteor/elm-app` which is the package we have just created (you can see it in the file `.meteor/packages`).
  -Then we call it to mount our Elm application on the node `document.getElementById("main")` (the one we have created in the `main.html` file)

   Now, if you start your meteor application by running the `meteor` command, on http://localhost:3000 you should see:
   
  
positive.code: - will add the `dist/elm-app.css` file in the client when it will be loaded,
  - have a main js file for this package called `dist/elm-app.js`.
  
  If you are using `elm-css` and if you don't need specific css classes in your app, you can remove `api.addFiles('dist/elm-app.css', 'client');` from the `package.js` file.

  === Create the app
  
  We will create our Elm application under the folder `packages/elm-app/app`.
  
  We need to install Elm:
  
  
negative.code: 
  === The CSS main file
  
  In the folder *meteor-elm-app/packages/elm-app/app*, create an empty *main.scss* SCSS file (or CSS if you prefer) that we will use later to add some style in our Elm application.
  
  NB: if you use *elm-css* and you don't need a stylesheet, skip this step and remove the line `api.addFiles('dist/elm-app.css', 'client');` in the *package.js* file
  
  === The Package mainModule
  
  In the folder *meteor-elm-app/packages/elm-app/app*, create a file *index.ts* that will *mount* our Elm application and export the *ports*.
  
  A simple version could:
