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
evalis unsafe if used improperly). Set up a file called.java.policyin 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 -
To run the tests:
lein test
