Installing Junebug

I’d like to install the Junebug wiki on my site (right at the root), but never having used Ruby on Rails before, I’m having trouble merging their installation instructions…

gem install sqlite3-ruby --source gem install junebug-wiki -y junebug testwiki cd testwiki ruby wiki run…with the Dreamhost wiki’s RoR instructions.

I think I understand how to set up my shell to install the gems, but I’m not sure what I should do instead of “ruby wiki run” to get Junebug going.
