As someone who already has the book, and is viewing the Quickstart as a way to get people introduced to it, it does the job well. This quickstart gives the overall rules for the game, including challenges, time, and related mechanics; character creation and two Clans, the Ventrue and Brujah; all the base Merits and Clan-specific Merits; appropriate Disciplines for those Clans; skills and trait descriptions; example equipment; and essentially everything you'd need to run a test game. Some things that are largely complex or wordy for the Quickstart (like Backgrounds and Status) is excised. The Quickstart advises you to build characters at the Ancilla generation and that's the only background talked about. Quite workable for test games to try out the rules.

Also as a bonus, if you already have a copy of the book, the Quickstart would make a great 'lite' copy for only the rules to have on hand for extras at a game.
