+Tempest Field Guide to Exceptions
+=================================
+
+
+What are these exceptions?
+--------------------------
+
+These exceptions are used by Tempest for covering OpenStack specific exceptional
+cases.
+
+How to add new exceptions?
+--------------------------
+
+Each exception-template for inheritance purposes should be added into 'base'
+submodule.
+All other exceptions can be added in two ways:
+- in main module
+- in submodule
+But only in one of the ways. Need to make sure, that new exception is not
+present already.
+
+How to use exceptions?
+----------------------
+
+Any exceptions from this module or its submodules should be used in appropriate
+places to handle exceptional cases.
+Classes from 'base' module should be used only for inheritance.
