 # Q&A
 
 ## What is open source and what isn't?
 
-About 75% of all non-content related Athena Crisis code is open source, including the core data structures, algorithms, game engine, rendering, AI, landing page and the map editor. Backend implementations such as user management, database, APIs, multiplayer, realtime spectating, translations, third-party integrations like Discord, server configuration and application wrappers for Steam or app stores are not open source. We aim to open source more of the game over time, but the content will remain the intellectual property of Nakazawa Tech KK and therefore not be open source. You can buy and enjoy [Athena Crisis on Steam Early Access](https://store.steampowered.com/app/2456430/Athena_Crisis/) or [buy it on athenacrisis.com](https://app.athenacrisis.com/checkout).

 ## Why did you open source Athena Crisis?
 
-[Nakazawa Tech](https://nkzw.tech) is an Open Core company. See [the Athena Crisis is Now Open Source blog post](https://cpojer.net/posts/athena-crisis-open-source) for more information.

 ## How is this codebase used at Nakazawa Tech?
 
 We use a monorepo for Athena Crisis at Nakazawa Tech and are syncing a portion of the codebase to this repository. Code merged into this open-source repository is automatically synced to the internal monorepo, and vice versa. Athena Crisis always runs the latest version of code from this repository in production.
 
 ### Why are some folders almost empty?
 
-To simplify dependency management with [`pnpm`](https://pnpm.io/), most of the internal `package.json` files and the `pnpm-lock.yaml` are public. This makes it easier to share code between the internal monorepo and this repository, but also means that there are some placeholders in this repository, most notably the `ares` and `artemis` packages.

This makes it easier to share code between the internal monorepo and this repository but leaves some placeholders in this repository, most notably the `ares` and `artemis` packages, which can be ignored.
 
 ## Why are packages named after Greek gods?
 
 Why not!? At some point it became necessary to split the codebase into multiple packages to share code between the client and server. The first package was named `athena`, and it was hard to come up with meaningful names for the other packages. We decided to name them after Greek gods because it seemed cute.
 
-Over time many pieces are expected to be extracted into separate packages and published on npm under the `@nkzw` organization. Please send a Pull Request if you find a piece of code that you think should be extracted into a separate package.

 ## How do assets work in this codebase?
 
-Assets are not part of this codebase. For testing, development and browsing, all assets are loaded remotely from the Athena Crisis servers.
