 # [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.
 
 # 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

-//! 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.

-// This is one of the parts that work around Chromium incorrectly implementing postMessage:
-// https://bugs.chromium.org/p/chromium/issues/detail?id=1075645
-//
-// rayon::ThreadPoolBuilder (used below) executes spawn handler to populate the worker pool,
-// and then blocks the current thread until each worker unblocks its (opaque) lock.
-//
-// Normally, we could use postMessage directly inside the spawn handler to
-// post module + memory + threadPtr to each worker, and the block the current thread.
-//
-// However, that bug means that postMessage is currently delayed until the next event loop,
-// which will never spin since we block the current thread, and so the other workers will
-// never be able to unblock us.
-//
-// To work around this problem, we:
-// 1) Expose `worker_initializer` that returns module + memory pair (without threadPtr)
-//    that workers can be initialised with to become native threads.
-//    JavaScript can postMessage this pair in advance, and asynchronously wait for workers
-//    to acknowledge the receipt.
-// 2) Create a global communication channel on the Rust side using crossbeam.
-//    It will be used to send threadPtr to the pre-initialised workers
-//    instead of postMessage.
-// 3) Provide a separate `start_main_thread` that expects all workers to be ready,
-//    and just uses the provided channel to send `threadPtr`s using the
-//    shared memory and blocks the current thread until they're all grabbed.
-// 4) Provide a `worker_initializer` that is expected to be invoked from various workers,
-//    reads one `threadPtr` from the shared channel and starts running it.
