To set up a problem you set up 1. a statement (one file) 1. test files (input/output pairs of files) 1. examples (like test files) 1. configure how many points the problem has and the interval when it is displayed (one file)

To use the server you 1. copy and paste the source code 1. select the language (c++, java, ocaml, haskell, perl, etc.) 1. click submit

The catch: it's hard to set up the server, and you have to be careful at security settings. For that, I recommend you use a virtual machine, like VMware.
