-This folder contains a self-contained sub-project for each encoder and decoder that squoosh supplies.
-
-## Build
-
-Each subproject can be built using [Docker](https://www.docker.com/) the following commands:
-
-```
-$ npm install
-$ npm run build
-```
-
-This will build two files: `<codec name>_<enc or dec>.js` and `<codec name>_<enc or dec>.wasm`. It will most likely be necessary to set [`Module["locateFile"]`](https://kripken.github.io/emscripten-site/docs/api_reference/module.html#affecting-execution) to successfully load the `.wasm` file. When the `.js` file is loaded, a global `<codec name>_<enc or dec>` is created with the same API as an [Emscripten `Module`](https://kripken.github.io/emscripten-site/docs/api_reference/module.html).
-
-Each codec will document its API in its README.

-
-Quantizes the given images, using at most `numColors`, a value between 2 and 256. `dithering` is a value between 0 and 1 controlling the amount of dithering. `RawImage` is a class with 3 fields: `buffer`, `width`, and `height`.
-
-### `RawImage zx_quantize(std::string buffer, int image_width, int image_height, float dithering)`

-# MozJPEG encoder
-
-- Source: <https://github.com/mozilla/mozjpeg>
-- Version: v3.3.1
-
-## Dependencies
-
-- Docker
-
-## Example
-
-See `example.html`
-
-## API
-
-### `int version()`
-
-Returns the version of MozJPEG as a number. va.b.c is encoded as 0x0a0b0c
-
-### `void free_result()`
-
-Frees the result created by `encode()`.
-
-### `Uint8Array encode(std::string image_in, int image_width, int image_height, MozJpegOptions opts)`
-
-Encodes the given image with given dimension to JPEG. Options looks like this:
-
-```c++
-struct MozJpegOptions {
-  int quality;
-  bool baseline;
-  bool arithmetic;
-  bool progressive;
-  bool optimize_coding;

-# OptiPNG
-
-- Source: <http://optipng.sourceforge.net/>
-- Version: v0.7.7
-
-## Dependencies
-
-- Docker
-
-## Example
-
-See `example.html`
-
-## API
-
-### `int version()`
-
-Returns the version of optipng as a number. va.b.c is encoded as 0x0a0b0c
-
-### `ArrayBuffer compress(std::string buffer, {level})`;
-
-`compress` will re-compress the given PNG image via `buffer`. `level` is a number between 0 and 7.
-
-### `void free_result()`
-
-Frees the result created by `compress()`.

-# WebP decoder
-
-- Source: <https://github.com/webmproject/libwebp>
-- Version: v1.0.2
-
-## Example
-
-See `example.html`
-
-## API
-
-### `int version()`
-
-Returns the version of libwebp as a number. va.b.c is encoded as 0x0a0b0c
-
-### `RawImage decode(std::string buffer)`
-
-Decodes the given webp buffer into raw RGBA. `RawImage` is a class with 3 fields: `buffer`, `width`, and `height`.
-
-### `void free_result()`
-
-Frees the result created by `decode()`.

-# WebP encoder
-
-- Source: <https://github.com/webmproject/libwebp>
-- Version: v1.0.2
-
-## Dependencies
-
-- Docker
-
-## Example
-
-See `example.html`
-
-## API
-
-### `int version()`
-
-Returns the version of libwebp as a number. va.b.c is encoded as 0x0a0b0c
-
-### `UInt8Array encode(uint8_t* image_buffer, int image_width, int image_height, WebPConfig config)`
-
-Encodes the given image with given dimension to WebP.
-
-### `void free_result()`
-
-Frees the last result created by `encode()`.
