+# Color convert
+
+Color convert is a set of conversion functions and automated conversions of
+color models and formats.
+
+### About
+
+Color convert does not rely on fragile practices, like converting ANSI16 to RGB.
+Why is this fragile? RGB is 16 million colors, converting to ANSI16 we get the
+code or ID of the color, not the color itself, so they are called system colors
+and are reserved by the system, changing depending on the runtime environment.
+
+- Quite a few conversions are planned for the future if anyone needs it.
+- All percentages are specified in the range `0` to `100`, this is more readable
+  to the user.
+- `HSV` and `HSB` are the same thing, but separated due to the frequent use of
+  both names.
+- `LAB` refers to `CIELAB` and `RGB` refers to `sRGB`, these are the most
+  frequent variants of the models that have become the basis, so do not need
+  direct name clarification.
+
+## Installation
+
+`CommonJS` (script directory) and `ModuleJS` (esm directory) support for
+`Node.js`, see [NPM page] for installation command. Also support for `Yarn` and
+other package managers or CDNs like `UNPKG`. For `Deno` reference see
+[module page], or use CDN like `esm.sh`.
+
+[NPM page]: https://www.npmjs.com/package/@chalkpot/color_convert
+[module page]: https://deno.land/x/chalkpot_color_convert
+
+## Usage
+
+```ts
+const green = rgbToAnsi16(0, 255, 0)[0];
+console.log(green); // 10
+console.log(wrapAnsi16(green)); // [92, 102]
+
+console.log(rgbToName(255, 0, 0)[0]); // red
+
+console.log(rgbToLab(255, 100, 25)); // [62.03..., 56.12..., 66.05...]
+```
