So based on what I've read so far for primers on chaos magic, I recommend starting with Condensed Chaos: An Introduction To Chaos Magic by Phil Hine, THEN getting the updated and revised and expanded editions of Liber Null and Psychonaut and also Liber Kaos by Peter J Carroll.
Caveats for Condensed Chaos:
misuse of "shaman" and similar terms (none of what is brought up relates to Tungusic peoples)
written by a neurotypical white English bisexual cisgender man, and boy howdy is the neurotypical part obvious in several areas
inconsistent capitalization for concepts, and also inconsistent comma usage
definitely a product of its time and not decolonized, which is a larger problem in chaos magic as a whole
Recommended Audience for Condensed Chaos:
those interested in servitors, sigils, or chaos magic more broadly
those who want to explore Jungian psychology in magic
As for Peter J Carroll's works... Basically the same as the above, yet also way more difficult to read if you're not used to old grimoire-esque language and writing styles.
I'd still genuinely recommend all three of these, just with the reminder to raise an eyebrow at some of the claims made.
The books I still have to read on chaos magic that I currently own are Hands-On Chaos Magic: Reality Manipulation Through The Ovayki Current by Andrieh Vitimus; Creating Magickal Entities: A Complete Guide to Entity Creation by David Michael Cunningham, Taylor Ellwood, and T Amanda R Wagener; and Magickal Servitors: Create Your Own Spirits To Attract Pleasure, Power and Prosperity by Damon Brand.
Plenty of reading left for me to do on this subject.
