+## Highlights
+
+- Expressive API
+- Highly performant
+- Ability to nest styles
+- [256/Truecolor color support](#256-and-truecolor-color-support)
+- Auto-detects color support
+- Doesn't extend `String.prototype`
+- Clean and focused
+- Actively maintained
+- [Used by ~50,000 packages](https://www.npmjs.com/browse/depended/chalk) as of January 1, 2020
+
+## Install
+
+```console
+$ npm install chalk
+```
+
+## Usage
+
+```js
+const chalk = require('chalk');
+
+console.log(chalk.blue('Hello world!'));
+```
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+const chalk = require('chalk');
+const log = console.log;
+
+// Combine styled and normal strings
+log(chalk.blue('Hello') + ' World' + chalk.red('!'));
+
+// Compose multiple styles using the chainable API
+log(chalk.blue.bgRed.bold('Hello world!'));
+
+// Pass in multiple arguments
+log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
+
+// Nest styles
+log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
+
+// Nest styles of the same type even (color, underline, background)
+log(chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+));
+
+// ES2015 template literal
+log(`
+CPU: ${chalk.red('90%')}
+RAM: ${chalk.green('40%')}
+DISK: ${chalk.yellow('70%')}
+`);
+
+// ES2015 tagged template literal
+log(chalk`
+CPU: {red ${cpu.totalPercent}%}
+RAM: {green ${ram.used / ram.total * 100}%}
+DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
+`);
+
+// Use RGB colors in terminal emulators that support it.
+log(chalk.keyword('orange')('Yay for orange colored text!'));
+log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
+log(chalk.hex('#DEADED').bold('Bold gray!'));
+```
+
+Easily define your own themes:
+
+```js
+const chalk = require('chalk');
+
+const error = chalk.bold.red;
+const warning = chalk.keyword('orange');
+
+console.log(error('Error!'));
+console.log(warning('Warning!'));
+```
+
+Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
+
+```js
+const name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> 'Hello Sindre'
+```
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.level
+
+Specifies the level of color support.
+
+Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.Instance({level: 0});
+```
+
+| Level | Description |
+| :---: | :--- |
+| `0` | All colors disabled |
+| `1` | Basic color support (16 colors) |
+| `2` | 256 color support |
+| `3` | Truecolor support (16 million colors) |
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
+
+### chalk.stderr and chalk.stderr.supportsColor
+
+`chalk.stderr` contains a separate instance configured with color support detected for `stderr` stream instead of `stdout`. Override rules from `chalk.supportsColor` apply to this too. `chalk.stderr.supportsColor` is exposed for convenience.
+
+## Styles
+
+### Modifiers
+
+- `reset` - Resets the current color chain.
+- `bold` - Make text bold.
+- `dim` - Emitting only a small amount of light.
+- `italic` - Make text italic. *(Not widely supported)*
+- `underline` - Make text underline. *(Not widely supported)*
+- `inverse`- Inverse background and foreground colors.
+- `hidden` - Prints the text, but makes it invisible.
+- `strikethrough` - Puts a horizontal line through the center of the text. *(Not widely supported)*
+- `visible`- Prints the text only when Chalk has a color level > 0. Can be useful for things that are purely cosmetic.
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+## Tagged template literal
+
+Chalk can be used as a [tagged template literal](https://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
+
+```js
+const chalk = require('chalk');
+
+const miles = 18;
+const calculateFeet = miles => miles * 5280;
+
+console.log(chalk`
+	There are {bold 5280 feet} in a mile.
+	In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
+`);
+```
+
+Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
+
+Template styles are chained exactly like normal Chalk styles. The following three statements are equivalent:
+
+```js
+console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
+console.log(chalk.bold.rgb(10, 100, 200)`Hello!`);
+console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
+```
+
+Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
+
+All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
+
+## 256 and Truecolor color support
+
+Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
+
+Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
+
+Examples:
+
+- `chalk.hex('#DEADED').underline('Hello, world!')`
+- `chalk.keyword('orange')('Some orange text')`
+- `chalk.rgb(15, 100, 204).inverse('Hello!')`
+
+Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
+
+- `chalk.bgHex('#DEADED').underline('Hello, world!')`
+- `chalk.bgKeyword('orange')('Some orange text')`
+- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
+
+The following color models can be used:
+
+- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
+- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
+- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
+- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
+- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
+- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model) - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
+- [`ansi`](https://en.wikipedia.org/wiki/ANSI_escape_code#3/4_bit) - Example: `chalk.ansi(31).bgAnsi(93)('red on yellowBright')`
+- [`ansi256`](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) - Example: `chalk.bgAnsi256(194)('Honeydew, more or less')`
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [Windows Terminal](https://github.com/microsoft/terminal) instead of `cmd.exe`.
+
+## Origin story
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.
+
+## chalk for enterprise
+
+Available as part of the Tidelift Subscription.

+## API
+
+### `ci.name`
+
+Returns a string containing name of the CI server the code is running on.
+If CI server is not detected, it returns `null`.
+
+Don't depend on the value of this string not to change for a specific
+vendor. If you find your self writing `ci.name === 'Travis CI'`, you
+most likely want to use `ci.TRAVIS` instead.
+
+### `ci.isCI`
+
+Returns a boolean. Will be `true` if the code is running on a CI server,
+otherwise `false`.
+
+Some CI servers not listed here might still trigger the `ci.isCI`
+boolean to be set to `true` if they use certain vendor neutral
+environment variables. In those cases `ci.name` will be `null` and no
+vendor specific boolean will be set to `true`.
+
+### `ci.isPR`
+
+Returns a boolean if PR detection is supported for the current CI server. Will
+be `true` if a PR is being tested, otherwise `false`. If PR detection is
+not supported for the current CI server, the value will be `null`.
+
+### `ci.<VENDOR-CONSTANT>`
+
+A vendor specific boolean constant is exposed for each support CI
+vendor. A constant will be `true` if the code is determined to run on
+the given CI server, otherwise `false`.
+
+Examples of vendor constants are `ci.TRAVIS` or `ci.APPVEYOR`. For a
+complete list, see the support table above.
+
+Deprecated vendor constants that will be removed in the next major
+release:
+
+- `ci.TDDIUM` (Solano CI) This have been renamed `ci.SOLANO`

+# jest-diff
+
+Display differences clearly so people can review changes confidently.
+
+The `diff` named export serializes JavaScript **values**, compares them line-by-line, and returns a string which includes comparison lines.
+
+Two named exports compare **strings** character-by-character:
+
+- `diffStringsUnified` returns a string.
+- `diffStringsRaw` returns an array of `Diff` objects.
+
+Three named exports compare **arrays of strings** line-by-line:
+
+- `diffLinesUnified` and `diffLinesUnified2` return a string.
+- `diffLinesRaw` returns an array of `Diff` objects.
+
+## Installation
+
+To add this package as a dependency of a project, run either of the following commands:
+
+- `npm install jest-diff`
+- `yarn add jest-diff`
+
+## Usage of `diff()`
+
+Given JavaScript **values**, `diff(a, b, options?)` does the following:
+
+1. **serialize** the values as strings using the `pretty-format` package
+2. **compare** the strings line-by-line using the `diff-sequences` package
+3. **format** the changed or common lines using the `chalk` package
+
+To use this function, write either of the following:
+
+- `const {diff} = require('jest-diff');` in CommonJS modules
+- `import {diff} from 'jest-diff';` in ECMAScript modules
+
+### Example of `diff()`
+
+```js
+const a = ['delete', 'common', 'changed from'];
+const b = ['common', 'changed to', 'insert'];
+
+const difference = diff(a, b);
+```
+
+The returned **string** consists of:
+
+- annotation lines: describe the two change indicators with labels, and a blank line
+- comparison lines: similar to “unified” view on GitHub, but `Expected` lines are green, `Received` lines are red, and common lines are dim (by default, see Options)
+
+```diff
+- Expected
++ Received
+
+  Array [
+-   "delete",
+    "common",
+-   "changed from",
++   "changed to",
++   "insert",
+  ]
+```
+
+### Edge cases of `diff()`
+
+Here are edge cases for the return value:
+
+- `' Comparing two different types of values. …'` if the arguments have **different types** according to the `jest-get-type` package (instances of different classes have the same `'object'` type)
+- `'Compared values have no visual difference.'` if the arguments have either **referential identity** according to `Object.is` method or **same serialization** according to the `pretty-format` package
+- `null` if either argument is a so-called **asymmetric matcher** in Jasmine or Jest
+
+## Usage of diffStringsUnified
+
+Given **strings**, `diffStringsUnified(a, b, options?)` does the following:
+
+1. **compare** the strings character-by-character using the `diff-sequences` package
+2. **clean up** small (often coincidental) common substrings, also known as chaff
+3. **format** the changed or common lines using the `chalk` package
+
+Although the function is mainly for **multiline** strings, it compares any strings.
+
+Write either of the following:
+
+- `const {diffStringsUnified} = require('jest-diff');` in CommonJS modules
+- `import {diffStringsUnified} from 'jest-diff';` in ECMAScript modules
+
+### Example of diffStringsUnified
+
+```js
+const a = 'common\nchanged from';
+const b = 'common\nchanged to';
+
+const difference = diffStringsUnified(a, b);
+```
+
+The returned **string** consists of:
+
+- annotation lines: describe the two change indicators with labels, and a blank line
+- comparison lines: similar to “unified” view on GitHub, and **changed substrings** have **inverse** foreground and background colors (that is, `from` has white-on-green and `to` has white-on-red, which the following example does not show)
+
+```diff
+- Expected
++ Received
+
+  common
+- changed from
++ changed to
+```
+
+### Performance of diffStringsUnified
+
+To get the benefit of **changed substrings** within the comparison lines, a character-by-character comparison has a higher computational cost (in time and space) than a line-by-line comparison.
+
+If the input strings can have **arbitrary length**, we recommend that the calling code set a limit, beyond which splits the strings, and then calls `diffLinesUnified` instead. For example, Jest falls back to line-by-line comparison if either string has length greater than 20K characters.
+
+## Usage of diffLinesUnified
+
+Given **arrays of strings**, `diffLinesUnified(aLines, bLines, options?)` does the following:
+
+1. **compare** the arrays line-by-line using the `diff-sequences` package
+2. **format** the changed or common lines using the `chalk` package
+
+You might call this function when strings have been split into lines and you do not need to see changed substrings within lines.
+
+### Example of diffLinesUnified
+
+```js
+const aLines = ['delete', 'common', 'changed from'];
+const bLines = ['common', 'changed to', 'insert'];
+
+const difference = diffLinesUnified(aLines, bLines);
+```
+
+```diff
+- Expected
++ Received
+
+- delete
+  common
+- changed from
++ changed to
++ insert
+```
+
+### Edge cases of diffLinesUnified or diffStringsUnified
+
+Here are edge cases for arguments and return values:
+
+- both `a` and `b` are empty strings: no comparison lines
+- only `a` is empty string: all comparison lines have `bColor` and `bIndicator` (see Options)
+- only `b` is empty string: all comparison lines have `aColor` and `aIndicator` (see Options)
+- `a` and `b` are equal non-empty strings: all comparison lines have `commonColor` and `commonIndicator` (see Options)
+
+## Usage of diffLinesUnified2
+
+Given two **pairs** of arrays of strings, `diffLinesUnified2(aLinesDisplay, bLinesDisplay, aLinesCompare, bLinesCompare, options?)` does the following:
+
+1. **compare** the pair of `Compare` arrays line-by-line using the `diff-sequences` package
+2. **format** the corresponding lines in the pair of `Display` arrays using the `chalk` package
+
+Jest calls this function to consider lines as common instead of changed if the only difference is indentation.
+
+You might call this function for case insensitive or Unicode equivalence comparison of lines.
+
+### Example of diffLinesUnified2
+
+```js
+import {format} from 'pretty-format';
+
+const a = {
+  text: 'Ignore indentation in serialized object',
+  time: '2019-09-19T12:34:56.000Z',
+  type: 'CREATE_ITEM',
+};
+const b = {
+  payload: {
+    text: 'Ignore indentation in serialized object',
+    time: '2019-09-19T12:34:56.000Z',
+  },
+  type: 'CREATE_ITEM',
+};
+
+const difference = diffLinesUnified2(
+  // serialize with indentation to display lines
+  format(a).split('\n'),
+  format(b).split('\n'),
+  // serialize without indentation to compare lines
+  format(a, {indent: 0}).split('\n'),
+  format(b, {indent: 0}).split('\n'),
+);
+```
+
+The `text` and `time` properties are common, because their only difference is indentation:
+
+```diff
+- Expected
++ Received
+
+  Object {
++   payload: Object {
+      text: 'Ignore indentation in serialized object',
+      time: '2019-09-19T12:34:56.000Z',
++   },
+    type: 'CREATE_ITEM',
+  }
+```
+
+The preceding example illustrates why (at least for indentation) it seems more intuitive that the function returns the common line from the `bLinesDisplay` array instead of from the `aLinesDisplay` array.
+
+## Usage of diffStringsRaw
+
+Given **strings** and a boolean option, `diffStringsRaw(a, b, cleanup)` does the following:
+
+1. **compare** the strings character-by-character using the `diff-sequences` package
+2. optionally **clean up** small (often coincidental) common substrings, also known as chaff
+
+Because `diffStringsRaw` returns the difference as **data** instead of a string, you can format it as your application requires (for example, enclosed in HTML markup for browser instead of escape sequences for console).
+
+The returned **array** describes substrings as instances of the `Diff` class, which calling code can access like array tuples:
+
+The value at index `0` is one of the following:
+
+| value | named export  | description           |
+| ----: | :------------ | :-------------------- |
+|   `0` | `DIFF_EQUAL`  | in `a` and in `b`     |
+|  `-1` | `DIFF_DELETE` | in `a` but not in `b` |
+|   `1` | `DIFF_INSERT` | in `b` but not in `a` |
+
+The value at index `1` is a substring of `a` or `b` or both.
+
+### Example of diffStringsRaw with cleanup
+
+```js
+const diffs = diffStringsRaw('changed from', 'changed to', true);
+```
+
+| `i` | `diffs[i][0]` | `diffs[i][1]` |
+| --: | ------------: | :------------ |
+| `0` |           `0` | `'changed '`  |
+| `1` |          `-1` | `'from'`      |
+| `2` |           `1` | `'to'`        |
+
+### Example of diffStringsRaw without cleanup
+
+```js
+const diffs = diffStringsRaw('changed from', 'changed to', false);
+```
+
+| `i` | `diffs[i][0]` | `diffs[i][1]` |
+| --: | ------------: | :------------ |
+| `0` |           `0` | `'changed '`  |
+| `1` |          `-1` | `'fr'`        |
+| `2` |           `1` | `'t'`         |
+| `3` |           `0` | `'o'`         |
+| `4` |          `-1` | `'m'`         |
+
+### Advanced import for diffStringsRaw
+
+Here are all the named imports that you might need for the `diffStringsRaw` function:
+
+- `const {DIFF_DELETE, DIFF_EQUAL, DIFF_INSERT, Diff, diffStringsRaw} = require('jest-diff');` in CommonJS modules
+- `import {DIFF_DELETE, DIFF_EQUAL, DIFF_INSERT, Diff, diffStringsRaw} from 'jest-diff';` in ECMAScript modules
+
+To write a **formatting** function, you might need the named constants (and `Diff` in TypeScript annotations).
+
+If you write an application-specific **cleanup** algorithm, then you might need to call the `Diff` constructor:
+
+```js
+const diffCommon = new Diff(DIFF_EQUAL, 'changed ');
+const diffDelete = new Diff(DIFF_DELETE, 'from');
+const diffInsert = new Diff(DIFF_INSERT, 'to');
+```
+
+## Usage of diffLinesRaw
+
+Given **arrays of strings**, `diffLinesRaw(aLines, bLines)` does the following:
+
+- **compare** the arrays line-by-line using the `diff-sequences` package
+
+Because `diffLinesRaw` returns the difference as **data** instead of a string, you can format it as your application requires.
+
+### Example of diffLinesRaw
+
+```js
+const aLines = ['delete', 'common', 'changed from'];
+const bLines = ['common', 'changed to', 'insert'];
+
+const diffs = diffLinesRaw(aLines, bLines);
+```
+
+| `i` | `diffs[i][0]` | `diffs[i][1]`    |
+| --: | ------------: | :--------------- |
+| `0` |          `-1` | `'delete'`       |
+| `1` |           `0` | `'common'`       |
+| `2` |          `-1` | `'changed from'` |
+| `3` |           `1` | `'changed to'`   |
+| `4` |           `1` | `'insert'`       |
+
+### Edge case of diffLinesRaw
+
+If you call `string.split('\n')` for an empty string:
+
+- the result is `['']` an array which contains an empty string
+- instead of `[]` an empty array
+
+Depending of your application, you might call `diffLinesRaw` with either array.
+
+### Example of split method
+
+```js
+import {diffLinesRaw} from 'jest-diff';
+
+const a = 'non-empty string';
+const b = '';
+
+const diffs = diffLinesRaw(a.split('\n'), b.split('\n'));
+```
+
+| `i` | `diffs[i][0]` | `diffs[i][1]`        |
+| --: | ------------: | :------------------- |
+| `0` |          `-1` | `'non-empty string'` |
+| `1` |           `1` | `''`                 |
+
+Which you might format as follows:
+
+```diff
+- Expected  - 1
++ Received  + 1
+
+- non-empty string
++
+```
+
+### Example of splitLines0 function
+
+For edge case behavior like the `diffLinesUnified` function, you might define a `splitLines0` function, which given an empty string, returns `[]` an empty array:
+
+```js
+export const splitLines0 = string =>
+  string.length === 0 ? [] : string.split('\n');
+```
+
+```js
+import {diffLinesRaw} from 'jest-diff';
+
+const a = '';
+const b = 'line 1\nline 2\nline 3';
+
+const diffs = diffLinesRaw(a.split('\n'), b.split('\n'));
+```
+
+| `i` | `diffs[i][0]` | `diffs[i][1]` |
+| --: | ------------: | :------------ |
+| `0` |           `1` | `'line 1'`    |
+| `1` |           `1` | `'line 2'`    |
+| `2` |           `1` | `'line 3'`    |
+
+Which you might format as follows:
+
+```diff
+- Expected  - 0
++ Received  + 3
+
++ line 1
++ line 2
++ line 3
+```
+
+In contrast to the `diffLinesRaw` function, the `diffLinesUnified` and `diffLinesUnified2` functions **automatically** convert array arguments computed by string `split` method, so callers do **not** need a `splitLine0` function.
+
+## Options
+
+The default options are for the report when an assertion fails from the `expect` package used by Jest.
+
+For other applications, you can provide an options object as a third argument:
+
+- `diff(a, b, options)`
+- `diffStringsUnified(a, b, options)`
+- `diffLinesUnified(aLines, bLines, options)`
+- `diffLinesUnified2(aLinesDisplay, bLinesDisplay, aLinesCompare, bLinesCompare, options)`
+
+### Properties of options object
+
+| name                              | default            |
+| :-------------------------------- | :----------------- |
+| `aAnnotation`                     | `'Expected'`       |
+| `aColor`                          | `chalk.green`      |
+| `aIndicator`                      | `'-'`              |
+| `bAnnotation`                     | `'Received'`       |
+| `bColor`                          | `chalk.red`        |
+| `bIndicator`                      | `'+'`              |
+| `changeColor`                     | `chalk.inverse`    |
+| `changeLineTrailingSpaceColor`    | `string => string` |
+| `commonColor`                     | `chalk.dim`        |
+| `commonIndicator`                 | `' '`              |
+| `commonLineTrailingSpaceColor`    | `string => string` |
+| `compareKeys`                     | `undefined`        |
+| `contextLines`                    | `5`                |
+| `emptyFirstOrLastLinePlaceholder` | `''`               |
+| `expand`                          | `true`             |
+| `includeChangeCounts`             | `false`            |
+| `omitAnnotationLines`             | `false`            |
+| `patchColor`                      | `chalk.yellow`     |
+
+For more information about the options, see the following examples.
+
+### Example of options for labels
+
+If the application is code modification, you might replace the labels:
+
+```js
+const options = {
+  aAnnotation: 'Original',
+  bAnnotation: 'Modified',
+};
+```
+
+```diff
+- Original
++ Modified
+
+  common
+- changed from
++ changed to
+```
+
+The `jest-diff` package does not assume that the 2 labels have equal length.
+
+### Example of options for colors of changed lines
+
+For consistency with most diff tools, you might exchange the colors:
+
+```ts
+import chalk = require('chalk');
+
+const options = {
+  aColor: chalk.red,
+  bColor: chalk.green,
+};
+```
+
+### Example of option for color of changed substrings
+
+Although the default inverse of foreground and background colors is hard to beat for changed substrings **within lines**, especially because it highlights spaces, if you want bold font weight on yellow background color:
+
+```ts
+import chalk = require('chalk');
+
+const options = {
+  changeColor: chalk.bold.bgYellowBright,
+};
+```
+
+### Example of option to format trailing spaces
+
+Because `diff()` does not display substring differences within lines, formatting can help you see when lines differ by the presence or absence of trailing spaces found by `/\s+$/` regular expression.
+
+- If change lines have a background color, then you can see trailing spaces.
+- If common lines have default dim color, then you cannot see trailing spaces. You might want yellowish background color to see them.
+
+```js
+const options = {
+  aColor: chalk.rgb(128, 0, 128).bgRgb(255, 215, 255), // magenta
+  bColor: chalk.rgb(0, 95, 0).bgRgb(215, 255, 215), // green
+  commonLineTrailingSpaceColor: chalk.bgYellow,
+};
+```
+
+The value of a Color option is a function, which given a string, returns a string.
+
+If you want to replace trailing spaces with middle dot characters:
+
+```js
+const replaceSpacesWithMiddleDot = string => '·'.repeat(string.length);
+
+const options = {
+  changeLineTrailingSpaceColor: replaceSpacesWithMiddleDot,
+  commonLineTrailingSpaceColor: replaceSpacesWithMiddleDot,
+};
+```
+
+If you need the TypeScript type of a Color option:
+
+```ts
+import {DiffOptionsColor} from 'jest-diff';
+```
+
+### Example of options for no colors
+
+To store the difference in a file without escape codes for colors, provide an identity function:
+
+```js
+const noColor = string => string;
+
+const options = {
+  aColor: noColor,
+  bColor: noColor,
+  changeColor: noColor,
+  commonColor: noColor,
+  patchColor: noColor,
+};
+```
+
+### Example of options for indicators
+
+For consistency with the `diff` command, you might replace the indicators:
+
+```js
+const options = {
+  aIndicator: '<',
+  bIndicator: '>',
+};
+```
+
+The `jest-diff` package assumes (but does not enforce) that the 3 indicators have equal length.
+
+### Example of options to limit common lines
+
+By default, the output includes all common lines.
+
+To emphasize the changes, you might limit the number of common “context” lines:
+
+```js
+const options = {
+  contextLines: 1,
+  expand: false,
+};
+```
+
+A patch mark like `@@ -12,7 +12,9 @@` accounts for omitted common lines.
+
+### Example of option for color of patch marks
+
+If you want patch marks to have the same dim color as common lines:
+
+```ts
+import chalk = require('chalk');
+
+const options = {
+  expand: false,
+  patchColor: chalk.dim,
+};
+```
+
+### Example of option to include change counts
+
+To display the number of changed lines at the right of annotation lines:
+
+```js
+const a = ['common', 'changed from'];
+const b = ['common', 'changed to', 'insert'];
+
+const options = {
+  includeChangeCounts: true,
+};
+
+const difference = diff(a, b, options);
+```
+
+```diff
+- Expected  - 1
++ Received  + 2
+
+  Array [
+    "common",
+-   "changed from",
++   "changed to",
++   "insert",
+  ]
+```
+
+### Example of option to omit annotation lines
+
+To display only the comparison lines:
+
+```js
+const a = 'common\nchanged from';
+const b = 'common\nchanged to';
+
+const options = {
+  omitAnnotationLines: true,
+};
+
+const difference = diffStringsUnified(a, b, options);
+```
+
+```diff
+  common
+- changed from
++ changed to
+```
+
+### Example of option for empty first or last lines
+
+If the **first** or **last** comparison line is **empty**, because the content is empty and the indicator is a space, you might not notice it.
+
+The replacement option is a string whose default value is `''` empty string.
+
+Because Jest trims the report when a matcher fails, it deletes an empty last line.
+
+Therefore, Jest uses as placeholder the downwards arrow with corner leftwards:
+
+```js
+const options = {
+  emptyFirstOrLastLinePlaceholder: '↵', // U+21B5
+};
+```
+
+If a content line is empty, then the corresponding comparison line is automatically trimmed to remove the margin space (represented as a middle dot below) for the default indicators:
+
+|         Indicator | untrimmed | trimmed |
+| ----------------: | :-------- | :------ |
+|      `aIndicator` | `'-·'`    | `'-'`   |
+|      `bIndicator` | `'+·'`    | `'+'`   |
+| `commonIndicator` | `' ·'`    | `''`    |
+
+### Example of option for sorting object keys
+
+When two objects are compared their keys are printed in alphabetical order by default. If this was not the original order of the keys the diff becomes harder to read as the keys are not in their original position.
+
+Use `compareKeys` to pass a function which will be used when sorting the object keys.
+
+```js
+const a = {c: 'c', b: 'b1', a: 'a'};
+const b = {c: 'c', b: 'b2', a: 'a'};
+
+const options = {
+  // The keys will be in their original order
+  compareKeys: () => 0,
+};
+
+const difference = diff(a, b, options);
+```
+
+```diff
+- Expected
++ Received
+
+  Object {
+    "c": "c",
+-   "b": "b1",
++   "b": "b2",
+    "a": "a",
+  }
+```
+
+Depending on the implementation of `compareKeys` any sort order can be used.
+
+```js
+const a = {c: 'c', b: 'b1', a: 'a'};
+const b = {c: 'c', b: 'b2', a: 'a'};
+
+const options = {
+  // The keys will be in reverse order
+  compareKeys: (a, b) => (a > b ? -1 : 1),
+};
+
+const difference = diff(a, b, options);
+```
+
+```diff
+- Expected
++ Received
+
+  Object {
+    "a": "a",
+-   "b": "b1",
++   "b": "b2",
+    "c": "c",
+  }
+```
