+# JSON5 – JSON for Humans
+
+[![Build Status](https://travis-ci.org/json5/json5.svg)][Build Status]
+[![Coverage
+Status](https://coveralls.io/repos/github/json5/json5/badge.svg)][Coverage
+Status]
+
+The JSON5 Data Interchange Format (JSON5) is a superset of [JSON] that aims to
+alleviate some of the limitations of JSON by expanding its syntax to include
+some productions from [ECMAScript 5.1].
+
+This JavaScript library is the official reference implementation for JSON5
+parsing and serialization libraries.
+
+[Build Status]: https://travis-ci.org/json5/json5
+
+[Coverage Status]: https://coveralls.io/github/json5/json5
+
+[JSON]: https://tools.ietf.org/html/rfc7159
+
+[ECMAScript 5.1]: https://www.ecma-international.org/ecma-262/5.1/
+
+## Summary of Features
+The following ECMAScript 5.1 features, which are not supported in JSON, have
+been extended to JSON5.
+
+### Objects
+- Object keys may be an ECMAScript 5.1 _[IdentifierName]_.
+- Objects may have a single trailing comma.
+
+### Arrays
+- Arrays may have a single trailing comma.
+
+### Strings
+- Strings may be single quoted.
+- Strings may span multiple lines by escaping new line characters.
+- Strings may include character escapes.
+
+### Numbers
+- Numbers may be hexadecimal.
+- Numbers may have a leading or trailing decimal point.
+- Numbers may be [IEEE 754] positive infinity, negative infinity, and NaN.
+- Numbers may begin with an explicit plus sign.
+
+### Comments
+- Single and multi-line comments are allowed.
+
+### White Space
+- Additional white space characters are allowed.
+
+[IdentifierName]: https://www.ecma-international.org/ecma-262/5.1/#sec-7.6
+
+[IEEE 754]: http://ieeexplore.ieee.org/servlet/opac?punumber=4610933
+
+## Short Example
+```js
+{
+  // comments
+  unquoted: 'and you can quote me on that',
+  singleQuotes: 'I can use "double quotes" here',
+  lineBreaks: "Look, Mom! \
+No \\n's!",
+  hexadecimal: 0xdecaf,
+  leadingDecimalPoint: .8675309, andTrailing: 8675309.,
+  positiveSign: +1,
+  trailingComma: 'in objects', andIn: ['arrays',],
+  "backwardsCompatible": "with JSON",
+}
+```
+
+## Specification
+For a detailed explanation of the JSON5 format, please read the [official
+specification](https://json5.github.io/json5-spec/).
+
+## Installation
+### Node.js
+```sh
+npm install json5
+```
+
+```js
+const JSON5 = require('json5')
+```
+
+### Browsers
+```html
+<script src="https://unpkg.com/json5@^2.0.0/dist/index.min.js"></script>
+```
+
+This will create a global `JSON5` variable.
+
+## API
+The JSON5 API is compatible with the [JSON API].
+
+[JSON API]:
+https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON
+
+### JSON5.parse()
+Parses a JSON5 string, constructing the JavaScript value or object described by
+the string. An optional reviver function can be provided to perform a
+transformation on the resulting object before it is returned.
+
+#### Syntax
+    JSON5.parse(text[, reviver])
+
+#### Parameters
+- `text`: The string to parse as JSON5.
+- `reviver`: If a function, this prescribes how the value originally produced by
+  parsing is transformed, before being returned.
+
+#### Return value
+The object corresponding to the given JSON5 text.
+
+### JSON5.stringify()
+Converts a JavaScript value to a JSON5 string, optionally replacing values if a
+replacer function is specified, or optionally including only the specified
+properties if a replacer array is specified.
+
+#### Syntax
+    JSON5.stringify(value[, replacer[, space]])
+    JSON5.stringify(value[, options])
+
+#### Parameters
+- `value`: The value to convert to a JSON5 string.
+- `replacer`: A function that alters the behavior of the stringification
+  process, or an array of String and Number objects that serve as a whitelist
+  for selecting/filtering the properties of the value object to be included in
+  the JSON5 string. If this value is null or not provided, all properties of the
+  object are included in the resulting JSON5 string.
+- `space`: A String or Number object that's used to insert white space into the
+  output JSON5 string for readability purposes. If this is a Number, it
+  indicates the number of space characters to use as white space; this number is
+  capped at 10 (if it is greater, the value is just 10). Values less than 1
+  indicate that no space should be used. If this is a String, the string (or the
+  first 10 characters of the string, if it's longer than that) is used as white
+  space. If this parameter is not provided (or is null), no white space is used.
+  If white space is used, trailing commas will be used in objects and arrays.
+- `options`: An object with the following properties:
+  - `replacer`: Same as the `replacer` parameter.
+  - `space`: Same as the `space` parameter.
+  - `quote`: A String representing the quote character to use when serializing
+    strings.
+
+#### Return value
+A JSON5 string representing the value.
+
+### Node.js `require()` JSON5 files
+When using Node.js, you can `require()` JSON5 files by adding the following
+statement.
+
+```js
+require('json5/lib/register')
+```
+
+Then you can load a JSON5 file with a Node.js `require()` statement. For
+example:
+
+```js
+const config = require('./config.json5')
+```
+
+## CLI
+Since JSON is more widely used than JSON5, this package includes a CLI for
+converting JSON5 to JSON and for validating the syntax of JSON5 documents.
+
+### Installation
+```sh
+npm install --global json5
+```
+
+### Usage
+```sh
+json5 [options] <file>
+```
+
+If `<file>` is not provided, then STDIN is used.
+
+#### Options:
+- `-s`, `--space`: The number of spaces to indent or `t` for tabs
+- `-o`, `--out-file [file]`: Output to the specified file, otherwise STDOUT
+- `-v`, `--validate`: Validate JSON5 but do not output JSON
+- `-V`, `--version`: Output the version number
+- `-h`, `--help`: Output usage information
+

+## Credits
+[Assem Kishore](https://github.com/aseemk) founded this project.
+
+[Michael Bolin](http://bolinfest.com/) independently arrived at and published
+some of these same ideas with awesome explanations and detail. Recommended
+reading: [Suggested Improvements to JSON](http://bolinfest.com/essays/json.html)
+
+[Douglas Crockford](http://www.crockford.com/) of course designed and built
+JSON, but his state machine diagrams on the [JSON website](http://json.org/), as
+cheesy as it may sound, gave us motivation and confidence that building a new
+parser to implement these ideas was within reach! The original
+implementation of JSON5 was also modeled directly off of Doug’s open-source
+[json_parse.js] parser. We’re grateful for that clean and well-documented
+code.

+[Max Nanasy](https://github.com/MaxNanasy) has been an early and prolific

+
+[Jordan Tucker](https://github.com/jordanbtucker) has aligned JSON5 more closely
+with ES5, wrote the official JSON5 specification, completely rewrote the
+codebase from the ground up, and is actively maintaining this project.
