 As basis for the information provided, the GraphQL API at [https://countries.trevorblades.com](https://countries.trevorblades.com) is used.
 More information can be found in the [corresponding GitHub repository](https://github.com/trevorblades/countries).

-## Exercise
-
-### Getting Started
-
-We're going to build a small webpage which displays continents and countries of the world.
-The basic structure is already there, you need to integrate a GraphQL API to fetch the data from.
-You can access GraphiQL of this API with the url [https://countries.trevorblades.com/](https://countries.trevorblades.com/).
-
-Play around with the API and get familiar with available queries and the fields of the returned objects as well as the relations.
-
-### Tasks
-
-Let's develop a webpage which displays continent and country information.
-You need to provide the needed GraphQL queries and set some information based on the response from the API.
-
-1. Add the necessary GraphQL queries in the JavaScript files
-2. Insert some information into the page based on the response from the API
-3. Test the wepage if all information is displayed correctly
