This is an information packet primarily meant for Christians, so it is heavily influenced by religious arguments. However, even for secular persons interested in discipline, there is good advice on how to structure it. Things like:

• Consent first.
• Start softly.
• Weekly open communication sessions.
• Keep notebooks.
• Set shared rules based on tangible goals.

It’s a bit cutsie in design and tone, but IMO still informative.
