 # BlitzKit
 
-Tools for everything and anything, World of Tanks Blitz.
+Your Blitz experience, elevated. https://blitzkit.app/.
 
-This GitHub repository contains the code for BlitzKit and all its services. If you are here, looking to use BlitzKit, go to https://blitzkit.app/.
+## Developing: Prerequisites
 
-If you intend to contribute to the code, note that you may need to check out sensitive, closed-source submodules to locally develop certain aspects of BlitzKit. Communicate with `@tresabhi` on Discord to get started or discuss sensitive content, such as environment variables or submodules.
+There's a few things you'll need to get started. If this is your first time working with BlitzKit, it's completely safe to ignore all optional prerequisites below to get things running as quickly as possible.
+
+### Bun
+
+[Bun](https://bun.sh/) is the package manager and runtime that BlitzKit uses.
+
+Ideally, you should also uninstall Node.js if you have it installed to avoid any cases where Node.js is used to run code instead of Bun which happens in some cases. But, this is not required and is unlikely to cause issues.
+
+### Protocol Buffer
+
+BlitzKit uses [Protocol Buffer's protoc CLI](https://protobuf.dev/installation/) to generate efficiently packed data structures to serve data to clients in place of JSON.
+
+### World of Tanks Blitz
+
+You will need a local installation of [World of Tanks Blitz](https://wotblitz.com/) for BlitzKit to build off.
+
+### aria2 (Optional)
+
+If you plan to use BlitzKit's client-management CLI for BlitzKit Previews, you will need to [get aria2](https://aria2.github.io/) to speed up your downloads.
+
+### libarchive (Optional)
+
+If you plan to use BlitzKit's client-management CLI for BlitzKit OpenTests, you will need to [get libarchive](https://www.libarchive.org/) to keep your downloads completely in-memory.
+
+### Linux (Optional)
+
+All work on BlitzKit is done on Linux and macOS. It is theoretically possible to work on Windows; please feel free to try and share your discoveries with us!
+
+## Developing: Setting Up
+
+Start by cloning the repository and changing directories.
+
+```bash
+git clone https://github.com/blitzkit/blitzkit.git
+cd blitzkit
+```
+
+> [!NOTE]
+> There is a closed source submodule under `packages/closed` that you can safely ignore. This sole purpose of this submodule is to provide `dvp.ts`, a proprietary Wargaming game asset tree compression tool. You will not need this at any point.
+
+Then, download the dependencies with Bun.
+
+```bash
+bun install
+```
+
+Finally, compile the proto files into TypeScript.
+
+```bash
+build build-protos
+```
+
+## Developing: Environment
+
+Go through the different packages in the `packages` directory and clone their respective `template.env`'s to `.env` files. Follow the instructions in the `.env` files to fill them out as much as you can.
+
+## Developing: Running
+
+Launching the website is as easy as running the `dev` script.
+
+```bash
+bun dev
+```
+
+If you ever make a change to any proto file, make sure to rebuild them.
+
+```bash
+build build-protos
+```
