+// ⚽️  Goal
+// --------
+
+// We want to create a webapp to reserve products (food).
+// Some ingredients we need: a store, products and reservations.
+// First of all we want a list of stores. After we have chosen
+// a store, we get a list of products (query) of that store.
+// We pick some products, pick a quantity, and we make a reservation (mutation)
+
+// 🏪  Exercise 1
+// --------------
+
+// 1) First we create two files. One for our type definitions, `typeDefs.js`,
+//    and one for our resolver functions, `resolvers.js`.
+// 2) Create a GraphQL type definition for our store. A store has an id and a name.
+// 3) Create a Query `stores` to get a list of stores.
+// 4) Create a resolver function that returns the list of stores.
+// 5) Try out the GraphQL query in the GraphQL Playground (🚀 http://localhost:4000/)
 
 // Type definitions define the "shape" of your data and specify
 // which ways the data can be fetched from the GraphQL server.
