Hay documentación sobre Drupal. Lo que no hay es una referencia que trate el core como lo que es: un sistema de software con arquitectura propia, contratos explícitos y decisiones de diseño que tienen consecuencias en el código que escribes encima.

Este libro cubre ese hueco. No explica cómo montar un sitio: explica cómo funciona el kernel por dentro, qué contrato expone cada servicio y por qué el sistema se comporta como se comporta. Son 1432 páginas y 254 capítulos organizados en seis partes, desde los subsistemas de `Drupal\\Component` —que son PHP puro y no saben que Drupal existe— hasta los 74 módulos del core, uno por capítulo.
