-Customized Fedora-based operating system distributed as an immutable

-root filesystem image.
-
-## Building
-
-Must run on a Fedora host or privileged container.
-
-Build the root filesystem image:
 
 ```sh
-make rootfs
+sudo dnf install -y \
+	ncurses-devel \
+	perl-ExtUtils-MakeMaker \
+	perl-FindBin \
+	perl-Thread-Queue \

-This will create an `_build/rootfs` directory containing the root filesystem
-hierarchy.  The `_build/rootfs/boot` directory contains the necessary files to
-boot the system:
-
-* `efi`: This directory contains the Raspberry Pi firmware files
-* `initramfs.img`: Early userspace image
-* `vmlinuz`: Kernel image
-* `basementhud.squashfs`: Root filesystem image
-
-The Raspberry Pi firmware, initramfs image, and kernel image files must be
-served by a TFTP, while the rootfs image is served by NBD.
-
-Build the initramfs image:
-
 ```sh
-make initramfs
+git clone git://git.buildroot.net/buildroot ~/src/buildroot
+```

+### Build the Initramfs
