Download and install leiningen.

Download and install mongodb.

The project uses clojail, which requires a security policy setup in your home directory (because Clojure's
eval
is unsafe if used improperly). Set up a file called.java.policy
in your home directory. The contents should look vaguely like this:grant { permission java.security.AllPermission; };
but see the readme of that project for more details.
-
cd to the 4clojure project directory and run
lein deps
. -
Start up your mongodb, if you don't have autostart:
mongod
-
For the first time use, you will need to load the problem data. Run the script
load-data.sh
:./load-data.sh

Run
lein ring server
