Where can I find the major features list, any document?

Actually, I want use Phabricator on intranet( IP address, https://192.168.1.10/) and internet(https://somedomain.corp...) with different URL, so I keep it empty.
If this is not a bug, can you add this to the section:Troubleshooting in diffusion_hosting.

Yes, but I don't know it's related to ssh service.
This problem spend me about 4 hours, I checked everything ...
