Based on a non-destructive workflow, the armature remains easily editable anytime after the generation. Then, edit the result if needed (if your character is not a biped/ or for more accuracy), eventually place the facial bones and other extra limbs, and generate the final rig. To speed up this process, the smart tool will automatically try to find the body parts locations for you (bipeds only so far). Position the reference bones so that they match your character proportions.
