  +=== Create a Meteor package
  +
  +This Meteor package will contain our Elm application.
  +Then we will use this package inside the Meteor application
  +
  +Let's start by creating some folders:
   ```shell
   mkdir -p packages/elm-app/{app,dist}
   ```
   
  -because we will build with parcel and not with meteor, we will create a new file at the root of the meteor-elm-app called `.meteorignore`
  -
  +The `app` folder will contain the sources of our Elm application (Elm, TS and CSS files).
  +The `dist` folder will contain the result of the build made by Parcel.
  +
  +Because we will build with Parcel and not with Meteor, we will create a new file at the root of the `meteor-elm-app` called `.meteorignore`
  +
  +```shell
  +#under meteor-elm-app
  +touch .meteorignore
  +```
  +
  +Then add this line inside this new file:
   ```
   /packages/elm-app/app/**/*
   ```
   
  -because we don't want to push the dist and the `elm-stuff` folders on our repository, we will add them in the .gitignore
  +Because we don't want to push the `dist` and the `elm-stuff` folders on our repository, we will add them in the `.gitignore` located under the folder `meteor-elm-app`
  +
   ```
   dist
   elm-stuff
   ```
   
  -create a file package.js inside this folder:
  +Now, let's create a `package.js` file in our package:
  +
  +```shell
  +#under meteor-elm-app/packages/elm-app
  +touch package.js
  +```
  +
  +And add the following content in this file:
   ```js
   Package.describe({
       name: 'elm-app',
  
positive.code:     return app.ports
  }
  ```
  
  === Build with parcel
  But... wait... why do we use Parcel? Why don't we use the Elm make command? Why don't we use the Meteor bundler for css?
  
negative.code: 
  NOTE: elm-format is not mandatory but you should use it with your IDE to format on save and avoid problem at compile time
  
  We will also create a `script` in the `package.json` to call Elm easily.
  In your package.json, add this `elm` script:
  ```json
  "scripts": {
      "elm": "cd packages/elm-app/app && elm",
      "start": "meteor run"
  },
  ```
  
  You can validate your script is well configured by running:
  ```shell
  meteor npm run elm -- --version
  ```
