## What it is
The WICG repository incubating and tracking the Web Components specifications, including Shadow DOM, Custom Elements, HTML Templates, and module proposals. It serves as the coordination hub for spec issues, explainers, and proposals that are progressively upstreamed into WHATWG and CSS WG standards.

## Use cases
- understand how shadow dom and custom elements specs work
- track the status of web components standardization proposals
- file or follow issues about web components browser features
- read explainers for html modules and css modules proposals
- find where a web components spec is maintained now
- propose new web platform component model features

## When to choose
- you are a browser vendor or spec author working on web components standards
- you need authoritative explainers and issue tracking for shadow dom or custom elements
- you want to propose or follow incubation of new component-model features

## When to avoid
- you want a library or framework to build components in your app today
- you need tutorials or beginner documentation rather than specifications
- you need a runnable tool rather than spec text and issue trackers
