Raphaël Monat enhanced the documentation for the ocaml/dune repository, focusing on the 'dirs' and 'include_subdirs' features to address common misconfigurations and streamline developer onboarding. Working primarily with reStructuredText (RST), Raphaël clarified directory naming conventions and introduced explicit warnings about potential issues when combining 'include_subdirs' with lexer or parser stanzas. This targeted documentation update aimed to reduce support overhead by providing clear, actionable guidance for users. The work demonstrated a strong attention to detail in technical writing and documentation, ensuring that the guidance aligned with existing feature areas and contributed to the overall stability of the Dune project.
