+# The flow-parser package
+
+This package contains the Flow parser in its compiled-to-JavaScript form.
+
+# What is Flow
+
+See [flow.org](https://flow.org/). The code for the Flow parser [lives on GitHub](https://github.com/facebook/flow/tree/master/src/parser).
+
+# What is the Flow Parser
+
+The Flow Parser is a JavaScript parser written in OCaml. It produces an AST that conforms to the [ESTree spec](https://github.com/estree/estree) and that mostly matches what [esprima](http://esprima.org/) produces. The Flow Parser can be compiled to native code or can be compiled to JavaScript using [js_of_ocaml](http://ocsigen.org/js_of_ocaml/). This npm package contains the Flow parser compiled to JavaScript.
+
+# Usage
+
+You can use the Flow parser in your browser or in node. To use in node you can just do
+
+```JavaScript
+require('flow-parser').parse('1+1', {});
+```
+
+To use in the browser, you can add
+
+```HTML
+<script src="flow_parser.js"></script>
+```
+
+which will make the `flow` object available to use like so:
+
+```JavaScript
+flow.parse('1+1', {});
+```
+
+## Options
+
+The second argument to `flow.parse` is the options object. Currently supported options:
+
+### Basic options
+* `types` (boolean, default `true`) - enable parsing of Flow types
+* `use_strict` (boolean, default `false`) - treat the file as strict, without needing a "use strict" directive
+* `comments` (boolean, default `true`) - attach comments to AST nodes (`leadingComments` and `trailingComments`)
+* `all_comments` (boolean, default `true`) - include a list of all comments from the whole program
+* `tokens` (boolean, default `false`) - include a list of all parsed tokens in a top-level `tokens` property
+
+### Language features
+* `enums` (boolean, default `false`) - enable parsing of [enums](https://flow.org/en/docs/enums/)
+* `match` (boolean, default `false`) - enable parsing of [match expressions and match statements](https://flow.org/en/docs/match/)
+* `components` (boolean, default `false`) - enable parsing of [component syntax](https://flow.org/en/docs/react/component-syntax/)
+* `assert_operator` (boolean, default `false`) - enable parsing of the assert operator
+* `esproposal_decorators` (boolean, default `false`) - enable parsing of decorators
