+This command lists errors for a deployed app.
+
+This is a best-effort implementation and an attempt to gather a number of tips
+& tricks for finding errors together into one convenient command. When an app
+is failing to deploy or having issues, it could be a lot of things.
+
+This command currently takes into account:
+
+		Is the service deployed?
+    Is the service killed by an OOM error?
+		Is the service reporting an error (like in "ps --no-trunc" output)
+		Is the service healthcheck failing? what are the healthcheck logs?
+
+Got any more ideas? Please let us know:

+
+This command is best accompanied by "abra app logs <app>" which may reveal
+further information which can help you debug the cause of an app failure via
+the logs.
