+# Architecture
+
+## Modules
+
+Basically minosoft consists of 3 models:
+
+- Core
+- Eros
+- Rendering
+
+To only start the core, you can start the jar with the `--headless` parameter.
+
+### Core
+
+The core should not depend on other modules (currently not true, but reduced to a minimum). It contains all the network code,
+account management, entity logic, pyhsics and a lot more.
+
+### Eros
+
+Eros is the main gui, you can refer to it as launcher or server list. It is mostly using the [mvc design pattern](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller).
+The model is not part of the package, mostly util classes or code from the core.
+
+### Rendering
+
+Rendering does not depend on Eros, it only depends on the core. It is written pretty much abstract and even/watcher driven.
+This module contains most of the part. It does everything rendering (aka. what you actually see from the game).
+
+It is also pretty dynamic, you could say that it also exists ot of modules. It also handles a lot of the logic.
+You can find more about it [here](/doc/rendering/ReadMe.md).
+
+## Networking
+
+Networking is sitting on top of [Netty](https://netty.io/).
+Every packet has its own class, all data is (due to compatibility and multi versioning) read manually from the buffer.
+Every packet needs to include all version checks (e.g. `if(versionId >= V_1_19)`). If a packet changed fundamentally in a version,
+there might be a legacy packet. Not all (but pretty much all) packets are implemented.
+
+Every packet has a handle function, the use of it is pretty much straight forward. Most of those handle functions trigger events,
+that might get handled by mods or other modules.
+
+## Version data
+
+Minosoft does not have all properties of blocks, items, ... hardcoded into it.
+There is a large data blob generated by [PixLyzer](https://gitlab.bixilon.de/bixilon/pixlyzer) that gets downloaded and
+loaded on demand.
+
+Personally I don't really like that design, but it allows multi versioning and the adaption of new versions really quick.
+
+## Assets
+
+Assets are downloaded directly from mojang. Those assets are then hashed (to prevent duplicated saving) and compressed with
+[zstd](https://en.wikipedia.org/wiki/Zstd). There are assets functions (e.g. sound). You can disable downloading of those assets
+if you don't need them. The textures and models are stored in the original minecraft jar, this file is getting downloaded,
+uncompressed and striped down. Original minecraft code never gets executed.
+
+Assets are getting manged by assets managers. There are a few of them. Because of that design, you can easily load resource packs.
+
+You can find more about assets [here](/doc/Assets.md)
