@whip113 would you suggest that we just add a bolded Note to this section to say something like:

If you add the Conjur buildpack to your manifest or cf push command but don't also explicitly include the language buildpack, Cloud Foundry will see that the Conjur buildpack is not a "final buildpack" and will fail to invoke it. To use this buildpack, you must follow the instructions for using multiple buildpacks and specify both the Conjur buildpack and the final, language buildpack for your app (in that order).

[whip113]

I think that would be perfect.
