[peterjunpark]

Motivation

Apply Google developer documentation style guide:

• Use sentence case for headings
• Use second person ("you") instead of passive or third person
• Use present tense and active voice
• Remove filler words and Latin abbreviations ("e.g." → "for example", "i.e." → "that is")
• Remove "please", "simply", "easy", "just"
• Use numbered lists for sequential steps
• Use Oxford comma consistently
