Include various changes for readability. Make bulleted list parallel.
Shorten long sentences. In some cases include articles and clarify
subject in sentences. Spell out "for example." Eliminate redundant
words / phrases. Per Matthias's recommendation, shuffle order of topics
and create two sections to focus first on general packaging principles,
and then Horizon specifics.
