     Configure quickly a unit operation
 
     This decorator help you to configure quickly the record of a unit operations.
 
     Argument:
-    entities    A list seperated by coma of entity types related to the unit
-    operation. The entity type is searched inside argument's names of the
-    decorated function. If something match, the argument value is added as
-    related entity.
+    entities    A list of entity types related to the unit operation. The entity
+    type is searched inside argument's names of the decorated function. If
+    something match, the argument value is added as related entity. If the
+    argument name is different you can specify it with a tuple
+    (argname, entity_type) instead of just put the entity type.
 
     exclude     Remove some arguments from the context. By default, arguments
     called 'password' and 'auth' are removed. If an argument is an object, you
     need to exclude it or create manually the unit operation without this
     decorator.
 
-    operation_key   Key describing the unit operation. If you want to display a
-    well formed description you should add a translation key like this
-    "log_" + operation_key in locales files.
+    operation_key   A key to describe the unit operation log used to create the
+    filename and search a translation. Please ensure that this key prefixed by
+    'log_' is present in locales/en.json otherwise it won't be translatable.
