# ReScript Documentation for LLMs > ReScript is a robustly typed language that compiles to efficient and human-readable JavaScript. It comes with a lightning fast compiler toolchain that scales to any codebase size. ## Documentation Sets This ReScript manual major version: v12 (current version). The root `/llms.txt` file is the default entry point and always describes the current stable manual. Use the files under `/llms/manual/v13/` (pre-release version) or `/llms/manual/v12/` (current version) when you want an explicit major-version path. These major-version paths use the latest generated documentation for that major version and avoid full patch numbers in the URL. ### Default Current Files - [LLMs index](https://rescript-lang.org/llms.txt): This file - [Complete current documentation](https://rescript-lang.org/llms/manual/llm-full.txt): The complete current ReScript documentation including all examples and additional content - [Abridged current documentation](https://rescript-lang.org/llms/manual/llm-small.txt): A minimal current version of the ReScript documentation, with the essential content for quick reference ## Individual Package Documentation - [ReScript React documentation](https://rescript-lang.org/llms/react/llms.txt): This is the developer documentation for ReScript React. ## Notes - The abridged documentation excludes the detailed examples and supplementary information - The complete documentation includes all content from the official documentation - Package-specific documentation files contain only the content relevant to that package - The content is automatically generated from the same source as the official documentation for the specific version ### Major Version Files - [v13 pre-release LLMs index](https://rescript-lang.org/llms/manual/v13/llms.txt): The LLM file list for the latest ReScript v13 pre-release documentation - [v13 pre-release complete documentation](https://rescript-lang.org/llms/manual/v13/llm-full.txt): The complete latest ReScript v13 pre-release documentation - [v13 pre-release abridged documentation](https://rescript-lang.org/llms/manual/v13/llm-small.txt): A minimal latest ReScript v13 pre-release reference - [v12 current LLMs index](https://rescript-lang.org/llms/manual/v12/llms.txt): The LLM file list for the current ReScript v12 documentation - [v12 current complete documentation](https://rescript-lang.org/llms/manual/v12/llm-full.txt): The complete current ReScript v12 documentation - [v12 current abridged documentation](https://rescript-lang.org/llms/manual/v12/llm-small.txt): A minimal current ReScript v12 reference
