 # GraphQL
 
+Our GraphQL API can be explored via GraphiQL at your instance's

+You can check all existing queries and mutations on the right side
+of GraphiQL in its **Documentation explorer**. It's also possible to
+write queries and mutations directly on the left tab and check
+their execution by clicking **Execute query** button on the top left:
