Write Docs

Write useful project documentation by reading the repository first. Default to improving existing docs before creating new files.

<required_reading> Before drafting or editing any document, read:

• references/elements-of-style.md
• the matching document reference for the target type

Required mapping:

• README.md -> references/readme.md
• PRODUCT.md -> references/product.md
• FEATURES.md -> references/features.md
• ARCHITECTURE.md -> references/architecture.md
• CONTRIBUTING.md -> references/contributing.md
• TUTORIAL.md -> references/tutorial.md
