Custom Font

Because it is so confusing include a custom font in an Ionic 2 project?
What would be the correct steps for this? My project uses beta 9.

Follow the steps, but for me does not work. The source that I use has NPM installation.

Sorted out. BETA 10

In ‘node_modules \ ionic angle \ fonts’, include your custom fonts,
.ttf, .woff. Create .scss file. =>

After the folder Theme includes the app.core.scss file the full address of where this sources.
Ex @import “…/…/node_modules/ionic-angular/fonts/.”;
