Quickstart docs

General MR

Summary

When you go through the quickstart documentation it asks you to go to checkout version 1.17.0. The thing is, since this guide is in the big bang repository the guide itself changes when you do this checkout and asks you to checkout version 1.15.0. This is confusing and will make the user unsure if any other steps they've done thusfar in the guide have been changed. Ideally we could have this file dynamically update to the most recent tag, but I wasn't sure how to do that with gitlab. Maybe the file can updated automatically on release?

For now this should fix the main issue which is the quickstart.md changing when the user does their checkout.
