The style is inconsistent. Some sentences begin with upper case. Some paragraphs end with a period. Dropping the traditional "capitalize first letter of every sentence" style is handy for tech documents which often begin sentences with identifiers which are confusing when capitalized (e.g. "git").

* I propose to keep starting sentences with lower case, but end all sentences with punctuation. (Even some paragraphs currently end with period.)

* Titles (headers) are capitalized.

* Some FAQ questions are capitalized, some not. I think they should be capitalized in traditional style. Rewording can avoid starting with an identifier (like "git"). The answers follow the (no initial capital) paragraph/sentence style above.
