## What it is
The source repository for Real World OCaml, 2nd edition, a comprehensive book teaching practical OCaml programming. It contains chapter text in markdown with validated code examples, plus tooling to build the book's HTML and PDF versions.

## Use cases
- learn OCaml from scratch
- find a practical OCaml tutorial book
- understand OCaml modules, functors, and GADTs
- learn how to build real applications in OCaml
- understand the OCaml compiler and runtime
- set up an OCaml development environment with opam

## When to avoid
- you need a quick reference manual rather than a tutorial
- you want Windows-native examples (Windows support is limited)
- you need up-to-date coverage of the latest OCaml versions

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: programming-languages, tutorials, education
- platform: cross-platform
- tags: ocaml, book, functional-programming, markdown, mdx, linux, macos
