What I always do is...

  1. Add > Armature > Human metarig. Then I have the pre-made human rig, complete to the facial features as well. There are animals rig too.
  2. Adjust the bones to the character.
  3. Parent the character to the rig and choose > With automatic weight
  4. Do some weight paint cleaning

You can delete the metarig or move it to another...whatever they're doing for layers now.
