 # Integration Dashboard
 
+This dashboard provides the statuses of ASKEM's TA1 services.
+Specifically, the dashboard indicates
+- If an operation works with `knowledge-middleare`
+- How long that operation takes to complete
+- The quality of the outputs (not yet implemented)
+
+Currently, the dashboard is testing `knowledge-middleware` integration
+but other services and TAs might be checked in the future.
