Integrating Jenkins CI with Jasmine and Phantomjs and github?

I am new to Jenkins and have just learned about unit testing my javascript code with Jasmine and Phantomjs. So far I have been able to run my unit test with phantomjs spec/run-jasmine.js spec/SpecRunner.html on the command line. However, I want to integrate my test with a Jenkins server I set up. Can some give me some detailed instructions on how to create a new job that will trigger my test to run everytime I push new code to my github repository? Also, what is needed in my repository (so far I have the actual application and the test in it).

I'm pretty new to this, just the more detailed and basic the better!

Thanks
