DESCRIPTION OF CHANGES: Original A1 appendix not needed since dependencies were added to build section. A1 section has been replaced with the "Coupled WRF | WRF-Hydro V5 Test Case User Guide" pdf which has been converted to rst format, Erin Dougherty did the original review of the document before conversion.

ISSUE: #793

The leaves us without an Appendix 1, which is awkward. I understand trying renumber everything afterward would be a pain, maybe we could put something else in as A1?

I like this idea! Replacing A1 will just make things easier. I guess then this PR needs the other appendixes reviewed first then I'll switch one in

@rcabell Ok, the updated "Coupled WRF | WRF-Hydro V5 Test Case User Guide" that Erin edited is now Appendix 1, so that will solve that issue. This PR should be good to merge once re-reviewed
