 # [Squoosh]!

-[Squoosh] is an image compression web app that reduces image sizes through numerous formats.
+[Squoosh] is an image compression web app that allows you to dive into the advanced options provided
+by various image compressors.

 # Privacy

-Squoosh does not send your image to a server. All image compression processes locally.
+Google Analytics is used to record the following:

-However, Squoosh utilizes Google Analytics to collect 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.

- [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.
+Image compression is handled locally; no additional data is sent to the server.

-# Developing
+# Building locally

-To develop for Squoosh:
+Clone the repo, and:

-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
-   ```
+```sh
+npm install
+npm run build
+```

-# Contributing
+You can run the development server with:

-Squoosh is an open-source project that appreciates all community involvement. To contribute to the project, follow the [contribute guide](/CONTRIBUTING.md).
+```sh
+npm start
+```
