LLM.txt & AI Crawler Setup Guide for Open source projects

Create a `/.well-known/ai.txt` file at the root of your project's documentation repository.

Include a brief, human-readable introduction to the project's purpose and primary technologies.

List markdown-style links to critical resources: main README, contribution guidelines, code of conduct, API docs, and community forums.

Add a 'Key Technologies' section detailing primary languages, frameworks, and databases used.

Include a 'Governance Model' section outlining release cycles, maintainer roles, and decision-making processes.

Add a 'Support Channels' section listing Discord, Slack, mailing lists, or Stack Overflow tags.

Implement `User-agent: *` or specific bot directives (e.g., `User-agent: GPT-Code-Reviewer`) in your `robots.txt`.

Use `Allow` directives to prioritize crawling of `/docs/`, `/examples/`, and key `/src/` directories.

Use `Disallow` directives for `/tests/`, `/build/`, or temporary/experimental branches not intended for general AI training.

Verify your crawler permissions and scope using tools like `wget --spider` or by simulating bot behavior in a staging environment.

Monitor server logs for bot activity patterns to ensure AI crawlers are accessing intended project areas and not overwhelming build servers.

Use distinct H1/H2 headings to clearly delineate major sections (e.g., 'Installation', 'Usage', 'API Reference', 'Contributing').

Employ Markdown lists (`-`, `*`, `1.`) for structured data points, parameters, and options within API documentation.

Utilize code blocks (```) with language specifiers (e.g., ````python`, ````javascript`) for syntax highlighting and type recognition.

For complex data structures (e.g., JSON payloads, configuration files), use fenced code blocks with appropriate language identifiers.

Ensure consistent use of anchor links (`#section-name`) for internal referencing, enabling bots to link directly to specific topics.

Segment documentation into logical, self-contained units (e.g., a single function's explanation, a specific configuration parameter). Aim for conceptual coherence rather than strict word counts.

Begin each significant section or snippet with a clear topic sentence or summary that states its primary purpose.

Avoid ambiguous pronoun references; explicitly name the project, module, function, or parameter being discussed (e.g., 'The `data_processor` module...', 'To configure the `api_key`...').

Use clear, concise language. Remove jargon where possible or define it immediately upon introduction.

Include practical, runnable code examples directly within the documentation for key functionalities, ensuring they are well-commented.
