The config to share target browsers and Node.js versions between different
front-end tools. It is used in:

* [Autoprefixer]
* [Babel]
* [postcss-preset-env]
* [eslint-plugin-compat]
* [stylelint-no-unsupported-browser-features]
* [postcss-normalize]
* [obsolete-webpack-plugin]

All tools will find target browsers automatically,
when you add the following to `package.json`:

```json
  "browserslist": [
    "defaults",
    "not IE 11",
    "maintained node versions"
  ]
```

Or in `.browserslistrc` config:

```yaml
# Browsers that we support

defaults
not IE 11
maintained node versions
```

Developers set their version lists using queries like `last 2 versions`
to be free from updating versions manually.
Browserslist will use [`caniuse-lite`] with [Can I Use] data for this queries.

Browserslist will take queries from tool option,
`browserslist` config, `.browserslistrc` config,
`browserslist` section in `package.json` or environment variables.
