Here is an intro to the somewhat analogous codegen from HOL4:
https://isabelle.in.tum.de/doc/codegen.pdf

AIUI, Isabelle adopts HOL4 (instead of, say, FOL or ZF or Leslie Lamport et al's HOL-TLA or Leslie Lamport et al's HOL-TLA+ or Peter Vincent Homeier et al's HOL-omega) as its default system of logic, even though these five & others are installable instead.
