+To use GraphQL Playground, we need 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

 ### Login Via GraphQL
 
-You can login by sending the query:
+You can register a user by sending the query:
 
 ```gql
-mutation ($email: String!, $password: String!) {
-  login(email: $email, password: $password)
+mutation {
+  login(email: "user@example.org", password: "1234")
 }
 ```
+
+Or use `"moderator@example.org"` or `"admin@example.org"` for the roll you need.
+
+If all goes well, you will receive a QGL response like:
+
+```json
+{
+  "data": {
+    "login": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6InUzIiwibmFtZSI6Ikplbm55IFJvc3RvY2siLCJzbHVnIjoiamVubnktcm9zdG9jayIsImlhdCI6MTY2MjAyMzMwNSwiZXhwIjoxNzI1MTM4NTA1LCJhdWQiOiJodHRwOi8vbG9jYWxob3N0OjMwMDAiLCJpc3MiOiJodHRwOi8vbG9jYWxob3N0OjQwMDAiLCJzdWIiOiJ1MyJ9.atBS-SOeS784HPeFl_5s8sRWehEAU1BkgcOZFD8d4bU"
+  }
+}
+```
+
+You can use this response to set an HTTP header when you click `HTTP HEADERS` in the footer.
+Just set it with the login token you received in response:
+
+```json
+{
+  "Authorization": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6InUzIiwibmFtZSI6Ikplbm55IFJvc3RvY2siLCJzbHVnIjoiamVubnktcm9zdG9jayIsImlhdCI6MTY2MjAyMzMwNSwiZXhwIjoxNzI1MTM4NTA1LCJhdWQiOiJodHRwOi8vbG9jYWxob3N0OjMwMDAiLCJpc3MiOiJodHRwOi8vbG9jYWxob3N0OjQwMDAiLCJzdWIiOiJ1MyJ9.atBS-SOeS784HPeFl_5s8sRWehEAU1BkgcOZFD8d4bU"
+}
+```
+
+This token is used for all other queries and mutations you send to the backend.
+
+## Query And Mutate
+
+When you are logged in and open a new playground tab by clicking "+", you can create a new group by sending the following mutation:
+
+```gql
+mutation {
+  CreateGroup(
+    # id: ""
+    name: "My Group"
+    # slug: ""
+    about: "We will save the world"
+    description: "<p class=\"\"><em>English:</em></p><p class=\"\">This group is hidden.</p><h3>What is our group for?</h3><p>This group was created to allow investigative journalists to share and collaborate.</p><h3>How does it work?</h3><p>Here you can internally share posts and comments about them.</p><p><br></p><p><em>Deutsch:</em></p><p class=\"\">Diese Gruppe ist verborgen.</p><h3>Wofür ist unsere Gruppe?</h3><p class=\"\">Diese Gruppe wurde geschaffen, um investigativen Journalisten den Austausch und die Zusammenarbeit zu ermöglichen.</p><h3>Wie funktioniert das?</h3><p class=\"\">Hier könnt ihr euch intern über Beiträge und Kommentare zu ihnen austauschen.</p>"
+    groupType: hidden
+    actionRadius: interplanetary
+    categoryIds: ["cat12"]
+  ) {
+    id
+    name
+    slug
+    createdAt
+    updatedAt
+    disabled
+    deleted
+    about
+    description
+    groupType
+    actionRadius
+    myRole
+  }
+}
+```
+
+You will receive the answer:
+
+```json
+{
+  "data": {
+    "CreateGroup": {
+      "id": "2e3bbadb-804b-4ebc-a673-2d7c7f05e827",
+      "name": "My Group",
+      "slug": "my-group",
+      "createdAt": "2022-09-01T09:44:47.969Z",
+      "updatedAt": "2022-09-01T09:44:47.969Z",
+      "disabled": false,
+      "deleted": false,
+      "about": "We will save the world",
+      "description": "<p class=\"\"><em>English:</em></p><p class=\"\">This group is hidden.</p><h3>What is our group for?</h3><p>This group was created to allow investigative journalists to share and collaborate.</p><h3>How does it work?</h3><p>Here you can internally share posts and comments about them.</p><p><br></p><p><em>Deutsch:</em></p><p class=\"\">Diese Gruppe ist verborgen.</p><h3>Wofür ist unsere Gruppe?</h3><p class=\"\">Diese Gruppe wurde geschaffen, um investigativen Journalisten den Austausch und die Zusammenarbeit zu ermöglichen.</p><h3>Wie funktioniert das?</h3><p class=\"\">Hier könnt ihr euch intern über Beiträge und Kommentare zu ihnen austauschen.</p>",
+      "groupType": "hidden",
+      "actionRadius": "interplanetary",
+      "myRole": "owner"
+    }
+  }
+}
+```
+
+If you look into the Neo4j database with your browser and search the groups, you will now also find your new group.
