Deploying on hosted server


I’m new to RoR. I’ve worked through a basic app running locally on my
Windows PC using InstantRails, now I want to try it online.

I use Servage as my host (shared hosting, Linux/Apache). I’ve already
developed a few PHP/MySQL projects and they offer RoR.

I am just not sure which parts of the Rails dev tree need to install,
and where, to get it to work.

Can anyone point me at a simple guide? The books I have don’t seem to
mention deployment at all.
