-Alternative expressions for netboot.

-In the future, I'd like to structure this as a module, to easily
-turn on recursive Nix builds, or target a ZFS filesystem, etc.

-Also, the future should include tests in this repo.

-## Included Module Expressions
-
-* `./quickly.nix` uses recursive Nix to build the initrd and squashfs
-  filesystems more quickly, allowing for faster iteration of images.
-  Initial testing reduced build time from 5-10 minutes per image to
-  15-30 seconds.
-
-  The `./size-test/build.sh` test is able to build an incremental
-  netboot image in just 12 seconds, and the initrd is not rebuilt.

 ## How to Use
 
-First set up recursive nix on your builder. Then:
+1. set up recursive nix on your builder (see below)
+2. add `quickly.nix` to your system's imports, like in
+   `./size-test/base.nix`
+3. then build your iPXE boot directory:
 
 ```
 $ nix-build '<nixpkgs/nixos>' -I nixos-config=./size-test/base.nix -A config.system.build.ipxeBootDir
 ```
 
-and boot off of `./result/netboot.ipxe`. The initial build may take
-a few minutes, but subsequent builds will only take a few seconds.
