-# lib-openarena
-OpenArena Engine
+# OpenArena for Unikraft
+This is the port of OpenArena for Unikraft as external library.
+
+## Build
+OpenArena depends on the following extern libraries, that need to
+be added to `Makefile`:
+
+* `libc`, e.g. `musl`
+* compression library, e.g. `libzlib`
+* network stack, e.g. `lwip`
+
+Before you proceed to writing your own application, you can use the `main()`
+function provided in the Nginx glue code by enabling it in its configuration
+menu.
+
+## Root filesystem
+### Creating the filesystem
+OpenArena needs a filesystem which should contain its configuration files for the server, along with textures files. Therefore, the filesystem needs to be created before
+running the VM. You can find an example in the `catalog-core` entry dedicated to OpenArena.
+
+### Using the filesystem
+Mounting the filesystem is a transparent operation. All you have to do
+is to provide the right Qemu parameters in order for Unikraft to mount
+the filesystem.  We will use the cpio support for filesystems and for
+this you will need to use the following parameters:
+
+```bash
+-initrd initrd.cpio \
+-append "vfs.fstab=[\"initrd0:/:extract::ramfs=1:\"]"
+```
+
+To enable cpio, you'll need to select the following `Config.uk` entries:
+
+```bash
+select LIBUKCPIO
+select LIBDEVFS
+select LIBDEVFS_AUTOMOUNT
+select LIBDEVFS_DEVSTDOUT
+select LIBVFSCORE
+select LIBVFSCORE_AUTOMOUNT_UP
+```
+
+## Further information
+Please refer to the `README.md` as well as the documentation in the `docs/`
+subdirectory of the main unikraft repository.
