 # OpenFusionClient
 
-Electron app for joining OpenFusion servers
+[![Current Release](https://img.shields.io/github/v/release/OpenFusionProject/OpenFusionClient?include_prereleases)](https://github.com/OpenFusionProject/OpenFusionClient/releases/latest) [![Discord](https://img.shields.io/badge/chat-on%20discord-7289da.svg?logo=discord)](https://discord.gg/DYavckB)[![License](https://img.shields.io/github/license/OpenFusionProject/OpenFusionClient)](https://github.com/OpenFusionProject/OpenFusionClient/blob/master/LICENSE.md)
+
+An Electron app that allows you to easily join FusionFall servers.
+
+It automatically installs FF's custom build of Unity Web Player, manages text files such as `assetInfo.php`/`loginInfo.php`, and embeds the game, all in a few clicks!
+
+For an overview of how the game client worked originally, please see [this section in the OpenFusion README](https://github.com/OpenFusionProject/OpenFusion#architecture).
+
+## Disclaimer
+
+This repository does not contain any code from the actual FusionFall game client. **Think of it more as a launcher:** it abstracts away having to use a NPAPI plugin capable web browser, along with having to host a HTTP server for it to connect to.
+
+In addition, if you are interested in contributing: do note that **this project likely cannot utilize more modern Javascript techniques**. In order to use NPAPI plugins, a very old version of Electron was needed (0.31.0). This limits the project to only a portion of ES5 in non-strict mode, and a reduced subset of Node/Electron APIs.
+
+## Usage
+
+Provided that you have npm installed, clone the repository, then run install like so:
+
+```
+git clone https://github.com/OpenFusionProject/OpenFusionClient.git
+npm install
+```
+
+After that has completed you can then test OpenFusionClient:
+
+```
+npm run start
+```
+
+If you would like to package it as a standalone win32 application:
+
+```
+npm run pack
+```
+
+You can then compress the application directory into a zip file and installer for distribution:
+
+```
+npm run dist
+```
+
+Before opening a PR or running pack/dist, please do a code formatting pass:
+
+```
+npm run prettier
+```
