This repository is a comprehensive, community-maintained cheat sheet for favicon sizes, types, and best practices. It covers everything from minimal modern setups (SVG favicons with dark mode support, 180x180 apple-touch-icon, manifest.json) to exhaustive legacy browser support across iOS, Android, Windows, and older browsers. The README includes detailed HTML markup, image creation instructions, ICO file specifications, helpful tools, and a FAQ. The only other file is a PDF (FaviconGuides.ai), an Adobe Illustrator vector graphic that visually documents favicon sizes. There is no executable code or software; the repo is purely a static reference document. Its quality lies in the depth, accuracy, and practical utility of the information, which is regularly updated to reflect modern standards.

Cookiecutter PyPackage is a cookiecutter template that generates a modern Python package project with production-ready tooling. It produces a src-layout package with a Typer CLI, pytest tests, Ruff linting, ty type checking, uv dependency management, and a justfile task runner. The generated project includes security-hardened GitHub Actions workflows for CI, PyPI publishing via Trusted Publishers, documentation deployment with Zensical, CodeQL and zizmor security scanning, and Dependabot for dependency updates. The template itself is a Python package with a CLI wrapper around cookiecutter, a development watcher for live template iteration, and a comprehensive post-generation hook that optionally sets up a GitHub repository, enables Pages, and creates the PyPI environment. The codebase demonstrates strong engineering practices: comprehensive test coverage, clear separation of concerns, and thoughtful security defaults. It is actively maintained with recent commits and a well-documented changelog.
