# Imported Documentation Cache
This directory contains a local cache of documentation that is sourced from external repositories (e.g., the standalone GN repository).
NOTE: This is a temporary solution so that coding agents can access vital docs about GN (until there is consistent access to web fetch for all).
The primary purpose of this cache is to provide a stable, in-tree knowledge base for development tools and AI assistants. By having a local copy of this essential documentation, tools can operate consistently without relying on network access, and AI assistants can be instructed to use this high-quality, version-controlled information to provide accurate and context-aware help for Chromium development.
The contents of this directory are managed by the script refresh_docs.py located in this same directory. This script fetches the documents listed in its manifest from their canonical sources.
Do not edit the files in this directory directly. Your changes will be overwritten the next time the refresh script is run. If you need to update or add a document, please modify the DOCUMENT_MANIFEST within refresh_docs.py.
The AI assistant's instructions for using this documentation are located in agents/prompts/chromium_knowledge_base.md. It is recommended to review that file for any necessary updates whenever the document manifest in refresh_docs.py is changed.
