 # [Squoosh]!
 
-[Squoosh] is an image compression web app that allows you to dive into the advanced options provided
-by various image compressors.
+[Squoosh] is an image compression web app that reduces image sizes through numerous formats.
+
+# API & CLI
+
+Squoosh has [an API](https://github.com/GoogleChromeLabs/squoosh/tree/dev/libsquoosh) and [a CLI](https://github.com/GoogleChromeLabs/squoosh/tree/dev/cli) to compress many images at once.
 
 # Privacy
 
-Google Analytics is used to record the following:
+Squoosh does not send your image to a server. All image compression processes locally.
 
-* [Basic visit data](https://support.google.com/analytics/answer/6004245?ref_topic=2919631).
-* Before and after image size once an image is downloaded. These values are rounded to the nearest
-  kilobyte.
-* If install is available, when Squoosh is installed, and what method was used to install Squoosh.
+However, Squoosh utilizes Google Analytics to collect the following:
 
-Image compression is handled locally; no additional data is sent to the server.
+- [Basic visitor data](https://support.google.com/analytics/answer/6004245?ref_topic=2919631).
+- The before and after image size value.
+- If Squoosh PWA, the type of Squoosh installation.
+- If Squoosh PWA, the installation time and date.
 
-# Building locally
+# Developing
 
-Clone the repo, and:
+To develop for Squoosh:
 
-```sh
-npm install
-npm run build
-```
+1. Clone the repository
+1. To install node packages, run:
+   ```sh
+   npm install
+   ```
+1. Then build the app by running:
+   ```sh
+   npm run build
+   ```
+1. After building, start the development server by running:
+   ```sh
+   npm run dev
+   ```
 
-You can run the development server with:
+# Contributing
 
-```sh
-npm start
-```
+Squoosh is an open-source project that appreciates all community involvement. To contribute to the project, follow the [contribute guide](/CONTRIBUTING.md).

+# Squoosh CLI
+
+Squoosh CLI is an _experimental_ way to run all the codecs you know from the [Squoosh] web app on your command line using WebAssembly. The Squoosh CLI uses a worker pool to parallelize processing images. This way you can apply the same codec to many images at once.
+
+Squoosh CLI is currently not the fastest image compression tool in town and doesn’t aim to be. It is, however, fast enough to compress many images sufficiently quick at once.
+
+## Installation
+
+The Squoosh CLI can be used straight from the command line without installing using `npx`:
+
+```
+$ npx @squoosh/cli <options...>
+```
+
+Of course, you can also install the Squoosh CLI:
+
+```
+$ npm i -g @squoosh/cli
+$ squoosh-cli <options...>
+```
+
+## Usage
+
+```
+Usage: squoosh-cli [options] <files...>
+
+Options:
+  -V, --version                                          output the version number
+  -d, --output-dir <dir>                                 Output directory (default: ".")
+  -s, --suffix <suffix>                                  Append suffix to output files (default: "")
+  --max-optimizer-rounds <rounds>                        Maximum number of compressions to use for auto optimizations (default: "6")
+  --optimizer-butteraugli-target <butteraugli distance>  Target Butteraugli distance for auto optimizer (default: "1.4")
+  --resize [config]                                      Resize the image before compressing
+  --quant [config]                                       Reduce the number of colors used (aka. paletting)
+  --rotate [config]                                      Rotate image
+  --mozjpeg [config]                                     Use MozJPEG to generate a .jpg file with the given configuration
+  --webp [config]                                        Use WebP to generate a .webp file with the given configuration
+  --avif [config]                                        Use AVIF to generate a .avif file with the given configuration
+  --jxl [config]                                         Use JPEG-XL to generate a .jxl file with the given configuration
+  --wp2 [config]                                         Use WebP2 to generate a .wp2 file with the given configuration
+  --oxipng [config]                                      Use OxiPNG to generate a .png file with the given configuration
+  -h, --help                                             display help for command
+```
+
+The default values for each `config` option can be found in the [`codecs.ts`][codecs.ts] file under `defaultEncoderOptions`. Every unspecified value will use the default value specified here. _Better documentation is needed here._
+
+## Auto optimizer
+
+Squoosh CLI has an _experimental_ auto optimizer that compresses an image as much as possible, trying to hit a specific [Butteraugli] target value. The higher the Butteraugli target value, the more artifacts can be introduced.
+
+You can make use of the auto optimizer by using “auto” as the config object.
+
+```
+$ npx @squoosh/cli --wp2 auto test.png
