+# YAML <a href="https://www.npmjs.com/package/yaml"><img align="right" src="https://badge.fury.io/js/yaml.svg" title="npm package" /></a>
+
+`yaml` is a definitive library for [YAML](https://yaml.org/), the human friendly data serialization standard.
+This library:
+
+- Supports both YAML 1.1 and YAML 1.2 and all common data schemas,
+- Passes all of the [yaml-test-suite](https://github.com/yaml/yaml-test-suite) tests,
+- Can accept any string as input without throwing, parsing as much YAML out of it as it can, and
+- Supports parsing, modifying, and writing YAML comments and blank lines.
+
+The library is released under the ISC open source license, and the code is [available on GitHub](https://github.com/eemeli/yaml/).
+It has no external dependencies and runs on Node.js as well as modern browsers.
+
+For the purposes of versioning, any changes that break any of the documented endpoints or APIs will be considered semver-major breaking changes.
+Undocumented library internals may change between minor versions, and previous APIs may be deprecated (but not removed).
+
+For more information, see the project's documentation site: [**eemeli.org/yaml**](https://eemeli.org/yaml/)
+
+To install:
+
+```sh
+npm install yaml
+```
+
+**Note:** These docs are for `yaml@2`. For v1, see the [v1.10.0 tag](https://github.com/eemeli/yaml/tree/v1.10.0) for the source and [eemeli.org/yaml/v1](https://eemeli.org/yaml/v1/) for the documentation.
+
+## API Overview
+
+The API provided by `yaml` has three layers, depending on how deep you need to go: [Parse & Stringify](https://eemeli.org/yaml/#parse-amp-stringify), [Documents](https://eemeli.org/yaml/#documents), and the underlying [Lexer/Parser/Composer](https://eemeli.org/yaml/#parsing-yaml).
+The first has the simplest API and "just works", the second gets you all the bells and whistles supported by the library along with a decent [AST](https://eemeli.org/yaml/#content-nodes), and the third lets you get progressively closer to YAML source, if that's your thing.
+
+```js
+import { parse, stringify } from 'yaml'
+// or
+import YAML from 'yaml'
+// or
+const YAML = require('yaml')
+```
