##### SUMMARY
<!--- Explain the problem briefly below, add suggestions to wording or structure -->
In the user module, in the docs for the password field, there is a link to instructions on how to create a password hash for the module to consume. Said link is broken, and gives a 404.


Cf. [the corresponding line in the user module](https://github.com/ansible/ansible/blob/2b0cd2c13f2021f839600d601f75dea2c0343ed1/lib/ansible/modules/user.py#L92)


> HINT: Did you know the documentation has an "Edit on GitHub" link on every page ?

this one doesn't, or i just could not find it : /

"""
    This is a Darwin macOS User manipulation class.
    Main differences are that Darwin:-
      - Handles accounts in a database managed by dscl(1)
      - Has no useradd/groupadd
      - Does not create home directories
      - User password must be cleartext
      - UID must be given
      - System users must ben under 500
    This overrides the following methods from the generic class:-
      - user_exists()
      - create_user()
      - remove_user()
      - modify_user()
