+# GraphQL Playground
+
+To use the GraphQL Playground we have to know some basics:
+
+## How To Login?
+
+At first we have to have a user of ocelot.social as whom we can login.
+The user can be created by seeding the Neo4j database from the backend or by several GraphQL mutations.
+
+### Seed The Neo4j Database
+
+In your browser you reach the GraphQL Playground under `http://localhost:4000/`
+if the database and the backend is running, see [backend](../../backend/README.md).
+You can find how to seed there as well.
+
+### Use GraphQL Mutations To Create A User
+
+TODO: Describe how to create a user by GraphQL mutations!
+
+### Login Via GraphQL
+
+You can login by sending the query:
+
+```gql
+mutation ($email: String!, $password: String!) {
+  login(email: $email, password: $password)
+}
+```
