 Data about continents, countries as well as currencies can be retrieved.
 
 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
