[Koha] Newbie questions re servers for Koha

[Tammy Lynne Kirk]

Hi,

I've been volunteered to set up an ILS for my niece's school.  She goes 
to a small montissori grammar school with a library of about 500 books 
(or less).  I looked into the open-source options and thought that I'd 
give Koha a try.  The main problem that I have right now, though, is 
that I'm not very familiar with how servers work.  Can I install the 
server software on one of the computers in the school's network 
(assuming they are networked) or will they need to buy an independent 
box to act as a server?

If the school is not networked, what do I do?  Can I run Koha on a 
stand-alone?

I've explored the documentations page but most of the stuff I've read 
there explains what to do AFTER you've installed Koha.  I really need 
help with installing Koha in a small school library that may not have a 
networked environment.

Thanks,
Tammy
