add harmony documentation from aragon?

https://help.aragon.org/article/118-aragon-client-with-harmony

we're getting some documentation up.... maybe we can test https://www.blog.pokt.network/pocket-network-decentralizes-harmonys-rpc-traffic/ to see if that works as well.... might be a good group of documentation pieces

maybe we can connect on how to keep it up when we add documentation (or if the URLs change?)
