[Contrib] Chapter conclusion style - what should we do?

Editors and writers with opinions, what do you think about this? We need a common way to end chapters, a conclusion of sorts. For example: - "In this chapter you learned ..." (Boilerplate concluding paragraph) - Summary of chapter themes - List of review questions (good for individual or group stud, etc.) - List of key terms What are your ideas? What do you like? We can apply whichever style for the preview release, so we'll be able to circulate it among all readers for feedback. I opened this issue to keep track of our decisions: https://github.com/theopensourceway/guidebook/issues/160 Regards, - Karsten -- Karsten Wade [he/him/his]| Senior Community Architect | @quaid Red Hat Open Source Program Office (OSPO) : @redhatopen https://community.redhat.com | https://next.redhat.com | https://osci.io https://theopensourceway.org | https://github.com/theopensourceway/guide
