 ## Code structure
 
 Each major component and library has its own subdirectory (kernel, userspace, libc, ...). Each directory contains directory *include*, which has **all** of the header files of the component. Every header is included by its absolute path.

+To test on real hardware, I have a script to generate a compressed ISO. The ISO can be copied directly to an USB drive with for example `dd`. The file is created at build/banan-os.iso and can be generated with
+```sh
+./bos iso
+```
+
 I have also created shell completion script for zsh. You can either copy the file in _script/shell-completion/zsh/\_bos_ to _/usr/share/zsh/site-functions/_ or add the _script/shell-completion/zsh_ to your fpath in _.zshrc_.
 
+### Package Manager
+
+banan-os uses xbps as its package manager for ports. All upstream ports are packaged into xbps packages hosted on a [repository on my server](https://packages.bananymous.com/banan-os). You can manage sysroot's xbps packages with `./bos` wrapper. You can use `xbps-install`, `xbps-remove` and `xbps-query` with repository and sysroot set to the correct values. For example to install xbps that can be used inside banan-os you can use
+```sh
+./bos xbps-install -S xbps
+```
+For xbps usage see [their documentation](https://docs.voidlinux.org/xbps/index.html).

 ## Contributing
 
 As the upstream is hosted on my server https://git.bananymous.com/Bananymous/banan-os, merging contributions is not as trivial as it would be on GitHub. You can still send PRs in GitHub in which case I should be able to download the diff and apply it manually. If you want, I can also provide you an account to my git server. In this case please contact me ([email](mailto:[email protected]), [discord](https://discord.gg/ehjGySwYdK)).
