-Todo.
+This operator will mirror the selected bones along the X axis based on Blender's
+bone :ref:`naming convention <armature-editing-naming-conventions>` for symmetrical 
+armatures, either from left to right or right to left, depending on the selection.
+
+   .. note::
+
+      If the side of the bone cannot be determined, it will be ignored by Symmetrize.
+
+Bones with the opposite names that don't yet exist will be created, and already
+existing ones will be overwritten.
+If matching bones are selected on both sides, mirroring will happen
+from right to left.
+
+Symmetrized bone and constraint properties will have the necessary changes to 
+mirror their behaviours.
+
+When symmetrizing bones with :doc:`Action Constraints </animation/constraints/relationship/action>`, 
+the necessary keyframes will be added to the target Action to result 
+in symmetrical movement when the Action is activated.
+
+   .. note::
+
+      Note that bone or constraint drivers will not be created or affected in any way.
