# Browserslist Lint
Check your [Browserslist](https://github.com/browserslist/browserslist/) config
with target browsers for popular mistakes.
```sh
npx browserslist-lint
```
Or try online: [`browsersl.ist`](https://browsersl.ist/)
Rules:
* `missedNotDead`: lack of `no dead` with queries like `last 2 versions`.
* `countryWasIgnored`: bad coverage in some country with >10M Internet users.
* `limitedBrowsers`: ignoring browsers diversity by calling only
a few browsers directly in config.
* `alreadyDead`: browser with `not` is already in `not dead` or `defaults`.
