-## API
-
-### Color parsing
-
-<details>
-  <summary><b><code>colord(input)</code></b></summary>
-
-Parses the given input and creates a new Colord instance. String parsing strictly conforms to [CSS Color Level Specifications](https://www.w3.org/TR/css-color-4/#color-type).
-
-```js
-import { colord } from "colord";
-
-// String input examples
-colord("#FFF");
-colord("#ffffff");
-colord("#ffffffff");
-colord("rgb(255, 255, 255)");
-colord("rgba(255, 255, 255, 0.5)");
-colord("rgba(100% 100% 100% / 50%)");
-colord("hsl(90, 100%, 100%)");
-colord("hsla(90, 100%, 100%, 0.5)");
-colord("hsla(90deg 100% 100% / 50%)");
-colord("tomato"); // requires "names" plugin
-
-// Object input examples
-colord({ r: 255, g: 255, b: 255 });
-colord({ r: 255, g: 255, b: 255, a: 1 });
-colord({ h: 360, s: 100, l: 100 });
-colord({ h: 360, s: 100, l: 100, a: 1 });
-colord({ h: 360, s: 100, v: 100 });
-colord({ h: 360, s: 100, v: 100, a: 1 });
-```
-
-Check out the ["Plugins"](#plugins) section for more input format examples.
-
-</details>
-
-<details>
-  <summary><b><code>getFormat(input)</code></b></summary>
-
-Returns a color model name for the input passed to the function. Uses the same parsing system as `colord` function.
-
-```js
-import { getFormat } from "colord";
-
-getFormat("#aabbcc"); // "hex"
-getFormat({ r: 13, g: 237, b: 162, a: 0.5 }); // "rgb"
-getFormat("hsl(180deg, 50%, 50%)"); // "hsl"
-getFormat("WUT?"); // undefined
-```
-
-</details>
-
-### Color conversion

-<details>
-  <summary><b><code>.toHex()</code></b></summary>

-
-```js
-colord("rgb(0, 255, 0)").toHex(); // "#00ff00"
-colord({ h: 300, s: 100, l: 50 }).toHex(); // "#ff00ff"

-```
-
-</details>
-
-<details>
-  <summary><b><code>.toRgbString()</code></b></summary>

-  <summary><b><code>names</code> (CSS color keywords)</b> <i>1.45 KB</i></summary>
-
-Provides options to convert a color into a [CSS color keyword](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value#color_keywords) and vice versa.
-
-```js
-import { colord, extend } from "colord";
-import namesPlugin from "colord/plugins/names";
-
-extend([namesPlugin]);
-
-colord("tomato").toHex(); // "#ff6347"
-colord("#00ffff").toName(); // "cyan"
-colord("rgba(0, 0, 0, 0)").toName(); // "transparent"
-colord("#fe0000").toName(); // undefined (the color is not specified in CSS specs)
-colord("#fe0000").toName({ closest: true }); // "red" (closest color)
-```

-  <summary><b><code>xyz</code> (CIE XYZ color space)</b> <i>0.7 KB</i></summary>
-
-Adds support of [CIE XYZ](https://www.sttmedia.com/colormodel-xyz) color model. The conversion logic is ported from [CSS Color Module Level 4 Specification](https://www.w3.org/TR/css-color-4/#color-conversion-code).
-
-```js
-import { colord, extend } from "colord";
-import xyzPlugin from "colord/plugins/xyz";
-
-extend([xyzPlugin]);
-
-colord("#ffffff").toXyz(); // { x: 95.047, y: 100, z: 108.883, a: 1 }
-colord({ x: 0, y: 0, z: 0 }).toHex(); // "#000000"

-## Types
-
-**Colord** is written in strict TypeScript and ships with types in the library itself — no need for any other install. We provide everything you need in one tiny package.
-
-While not only typing its own functions and variables, **Colord** can also help you type yours. Depending on the color space you are using, you can also import and use the type that is associated with it.
-
-```ts
-import { RgbColor, RgbaColor, HslColor, HslaColor, HsvColor, HsvaColor } from "colord";
-
-const foo: HslColor = { h: 0, s: 0, l: 0 };
-const bar: RgbColor = { r: 0, g: 0, v: 0 }; // ERROR
-```
