The documentation needs work for begginers

After reading through the intro material and other pages on the webiste, I have no idea how to develop with karma. The most I can figure out from karma's website is how to start the karma server. After that, what do I do? How do i run tests in a way where I can step through code in the browser running the test?

Also, there is 0 documentation on how to interpret karma's output. It isn't self explanatory. Is everything that's outputting a failed test? How bout some screen shots that explain some of these things.
