Minor edits to first 2 chapters
Created by: ogryzek
Some minor edits to the first 2 chapters, which include
- Correcting typos
- Making style consistent (e.g. "The answer is: yes, it is." vs "The answer is: Yes, it is.")
- Removing periods at the end of bullet points
Note: I've tried to ignore styling choices, such as the use of colons before answers versus commas, quotations, or just statements, e.g. "The answer is yes." or whether there should be grammatical consistency with sentences that lead into a bulleted-list, which may be worthy of consideration at some point.
