-Google Analytics is used to record the following:
-
-* [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.
-
-Image compression is handled locally; no additional data is sent to the server.
-
-# Building locally
-
-Clone the repo, and:
-
-```sh
-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).

+# OptiPNG
+
+- Source: <https://sourceforge.net/project/optipng>
+- 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()`.

-//! This is a module that provides `malloc` and `free` for `libdeflate`.
-//! These implementations are compatible with the standard signatures
-//! but use Rust allocator instead of including libc one as well.
-//!
-//! Rust allocator APIs requires passing size and alignment to the
-//! `dealloc` function. This is different from C API, which only
-//! expects a pointer in `free` and expects allocators to take care of
-//! storing any necessary information elsewhere.
-//!
-//! In order to simulate C API, we allocate a `size_and_data_ptr`
-//! of size `sizeof(usize) + size` where `size` is the requested number
-//! of bytes. Then, we store `size` at the beginning of the allocated
-//! chunk (within those `sizeof(usize)` bytes) and return
-//! `data_ptr = size_and_data_ptr + sizeof(usize)` to the calleer:
-//!
-//! [`size`][...actual data]
-//! -^------------------ `size_and_data_ptr`
-//! ---------^---------- `data_ptr`
-//!
-//! Then, in `free`, the caller gives us `data_ptr`. We can subtract
-//! `sizeof(usize)` back and get the original `size_and_data_ptr`.
-//! At this point we can read `size` back and call the Rust `dealloc`
-//! for the whole allocated chunk.
-//!
-//! I've raised an upstream issue to hopefully make this easier in
-//! future: https://github.com/ebiggers/libdeflate/issues/62
