## What it is
GitHub's official collection of .gitignore file templates for many languages, frameworks, editors, and operating systems. It powers the .gitignore template chooser on GitHub.com and can be copied into any Git repository.

## Use cases
- find a gitignore template for a python project
- ignore node_modules and build artifacts in git
- set up a global gitignore for my editor
- stop committing IDE files to git
- get a gitignore template when creating a new repo

## When to choose
- you are starting a new project and want sensible ignore rules for your language or tool
- you need editor or OS-specific ignore rules for a global gitignore
- you want the canonical templates GitHub itself uses

## When to avoid
- you need programmatically generated or highly customized ignore rules
- your tooling already generates .gitignore files automatically (e.g. scaffolding CLIs)

## Facets
- artifact type: dataset
- maturity: stable
- function: version-control, developer-tools, configuration-management
- domain: developer-tools, version-control
- platform: cross-platform, cli
- tags: gitignore, git, templates, boilerplate
