 # Memgraph quality assurance
+
+In order to test dressipi's queries agains memgraph the following commands have
+to be executed:
+    1. ./init [Dxyz] # downloads query implementations + memgraph
+                     # (the auth is manually for now) + optionally user can
+                     # define arcanist diff which will be applied on the
+                     # memgraph source code
+    2. ./run         # compiles and runs database instance, also runs the
+                     # test queries
+
+TODO: automate further
