-All build instructions for codecs are written using [Nix]. If you have Nix installed, you can rebuild the WebAssembly binaries by running:
-
-```sh
-# Build the codec
-cd codec/<codec>
-nix run '.#updateRepoBinaries'

+# 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

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes

+
+   3. Grant of Patent License. Subject to the terms and conditions of

+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
