## Building instructions for Debian Linux distribution series(tested on Debian 12.5 stable):
### Dependences package install:
* on debian
```bash
sudo apt install libwayland-dev libx11-dev libxkbcommon-dev libxrandr-dev libxinerama-dev libxcursor-dev libxi-dev
```
* on archlinux
If you have been using GUI on archlinux, you shouldn't install any.
Or you shoud install Desktop Environment.
### Clone and Build:
```bash
git clone https://git.suthby.org:2024/SuthbyPublic/JungleOpenSourceProjectRepo.git --recurse-submodules
