First, a lecture given by the father of the movement, named Peter J. Carroll, called General Considerations on the Philosophy and Practice of Magick. You can find it in three parts on Youtube.

Second, check out his book Liber Null and Psychonaut. The book remains in print and can easily be found for download as a pdf. (Though complete versions can be elusive for some reason when downloading it.) Since 1987, Liber Null remains the basic primer for those wishing to learn about chaos magick.
I turned to chaos magick after my continued frustration with the sources for ceremonial magick. I find the forms and conventions of ceremonial magick highly effective, but despise the usual sources (Golden Dawn, Crowley), for being moribund in Judaic-Christian symbolism and theology. Most hermetic practices insist on a devotion to their way of doing things, often designed to inflate the egos of the magicians in charge of their particular society. Chaos magick allowed me to tap into the resources created by these magicians, without being enslaved by them.
Let me know if you would like more resources or have other questions.
