Current guidance

Dear friends at Dropbox and Sentry (cc @dcramer),

I've just recently finished up setting up Sentry and Phabricator in a kubernetes cluster, and for all that hard work I'd like to be able to use them together.

I see that this repo's readme is much easier to execute (copy some files, use GUI), compared to [sentry-phabricator](https://github.com/getsentry/sentry-phabricator) which would require me to build a new docker image for sentry with the pip install. And beyond that, why 2 different ways? This is simply confusing.

Please advise: what is the current way to get the most out of these two beautiful tools working together?

Start with this repository's README and compare its setup with the linked sentry-phabricator project. Determine which integration path is current and document the recommended way to use Sentry with Phabricator in a Kubernetes deployment, including why the approaches differ.
