+  title: Executes flow on flow trigger with ExecutionNamespace condition
+  description: >-
+    This flow trigger executes the flow based on the ExecutionNamespace condition. 
+    When any flow within the namespace as specified under the `namespace` in the 
+    ExecutionNamespace condition enters into the state specified under the `states` 
+    attribute of the Flow trigger, this flow will get triggered.
+
+    In this case, when any flow within namespace having prefix (as `comparison` 
+    attribute is set to `PREFIX`) `company.engineering` enters the `FAILED` state as 
+    defined in the `states` attribute, this flow will get triggered. This flow will send
+    a slack message about the flow execution that has failed, and in turn resulted in 
+    the triggering of this flow.
+
+    With ExecutionNamespace condition, you can enforce the condition on flow trigger that 
+    is based on the namespace of another flow.
