Natural Docs is an open-source documentation generator for multiple programming languages. You document your code in a natural syntax that reads like plain English. Natural Docs then scans your code and builds high-quality HTML documentation from it. SourceForge houses the source code and issue database for the old Perl version of Natural Docs, version 1.52. It is still available but no longer being updated. Please see NaturalDocs.org for the 2.x source code and issue database. However, you can still download the both the old and the new 2.x releases of Natural Docs here.

Docco is a documentation generator by Jeremy Ashkenas that embraces the literate-programming style: it takes your source code and produces annotated HTML documentation that shows your comments side-by-side with your code. The idea is to read code like a book — commentary on one side, code on the other — which helps reviewers and learners understand intent and implementation simultaneously. It supports many languages (via configuration) and is intentionally quick and dirty, prioritizing lightweight output rather than heavy tooling. For teams that favour documentation that stays close to the codebase (rather than entirely separate docs), Docco offers a pragmatic route to keep documentation aligned with implementation. Because the output is browser-readable, it can live in your repository or website and be regenerated easily. It’s particularly useful for open-source projects, teaching code, or scaffolding codebases where reader orientation matters.

The project is to translate latest vim help documentations into simplified Chinese.

AsciiDoc is a presentable text document format for writing articles, UNIX man pages and other small to medium sized documents. The asciidoc(1) command translates AsciiDoc files to HTML, DocBook and LinuxDoc formats.

Foswiki is an Enterprise wiki, typically used to run a collaboration platform, knowledge base or document management system. Users can create wiki applications using the Topic Markup Language, and developers can extend its functionality with plugins. Foswiki stands for "Free and Open Source" wiki to emphasize its commitment to Open Source software.

This repository contains the source for the Express web site and documentation, the canonical reference for developers using the Express framework. It organizes material into API reference, getting-started guides, best practices, and topic-focused explanations such as routing, middleware, error handling, templating, and performance. Versioned docs help readers match API behavior to the framework version they’re running, reducing confusion during upgrades. The site showcases common patterns through concise examples, making it easy to translate concepts into working code. In addition to core Express usage, the documentation surfaces ecosystem guidance on things like security headers, structured logging, and integration with view engines or ORMs. Because it is open to community contributions, the documentation evolves alongside Express itself, reflecting real-world questions and solutions.

docbook2X converts DocBook documents to man and Texinfo format.

The eng-practices project by Google is a public repository that documents the company’s established engineering best practices, accumulated through years of large-scale software development across diverse teams and languages. Its purpose is to share Google’s collective experience in areas such as code review, collaboration, and quality assurance with the broader software engineering community. The repository provides practical guidelines designed to help developers and reviewers produce cleaner, more maintainable, and higher-quality code. It includes Google’s comprehensive Code Review Guidelines, split into two major sections: The Code Reviewer’s Guide and The Change Author’s Guide, which detail the expectations and processes for both reviewers and authors. Additionally, it explains key terminology and practices commonly used within Google to make the documentation accessible to external audiences.

nginx-admins-handbook is a practical, in-depth guide for configuring, securing, and operating NGINX across real-world deployments. It distills years of research, notes, and field experience into a single handbook that complements the official docs with concrete rules, explanations, and curated external references. The handbook spans fundamentals and advanced topics alike, from HTTP and SSL/TLS basics to reverse proxy patterns, performance tuning, debugging workflows, and hardening strategies. A centerpiece is its prioritized checklist of 79 rules, grouped by criticality, helping readers focus on what most impacts security, reliability, and speed. Instead of copy-paste snippets in isolation, it emphasizes understanding trade-offs, avoiding common pitfalls, and balancing security with usability. Designed for system administrators and web application engineers, it aims to be a living companion that encourages experimentation, measurement, and continuous improvement of NGINX configurations

og-aws (The Open Guide to Amazon Web Services) is a community-maintained reference that consolidates tips, best practices, and practical knowledge for effectively using AWS.
