The README now lists what zregex is written against: PCRE2's pattern and API documentation as the specification, Thompson and Cox for the designs the Pike VM, lazy DFA and backtracker follow, the Unicode Character Database for case folding, POSIX for the bracket classes, and the Intel, Arm, Apple and Microsoft documentation behind the JIT. The same list is a new zregex collection in Zotero, with the Intel manual's PDF attached.
