`npm link` doesn't work as expected due to the `devDependency` on `@angular/core`. This is the work around...
npm run build.link ../ionic-conference-app
When the command above is ran from the `angular` directory, it will build `@ionic/angular` and copy the `dist` directory to the correct location of another local project. In the example above, the end result is that it copies the `dist` directory to `../ionic-conference-app/node_modules/@ionic/angular/dist`. The path given should be relative to the root of this mono repo.
The `package.json` file in this directory references __Ionic 3__ and is in here to get GitHub to properly show the Used By counts on the repo. __Do not remove it!__
