 ## The idea description
 
-The main goal of our app is to help travelers to visualise their past and future travels. That actually may sound a bit too official so basically we're building a digital scratch map. Our users will see a world map where they can mark countries they previously visited and countries they would like to visit in future. And of course our users should be able to save their progress. I think that's gonna be enough for the beginning, so let's create some user stories.
