 Because the Linux kernel exposes BPF helpers functions which are only
 available to GPL-licensed programs, BPFnative provides the option to allow BPF
 kernels to be generated under the GPL license, or whatever license is
-specified to the `bpfgen()` function. The subsequently generated kernel and
-source that generates would then be (probably) considered to be licensed as
+provided to `bpffunction()`. The subsequently generated kernel and

 BPFnative itself is of course just a compiler, so it may retain its MIT
 license. However, users should keep in mind that whatever license they specify
-to the `bpfgen()` function is the license that they must adhere to. This means

 BPFnative's compiler, the user would be obligated to adhere to the terms of
 the GPL license, and specifically, would be required to provide the source

 # BPFnative.jl
 
-## Instructions for use
-* Recompile Julia's LLVM with the appropriate line in deps/llvm.mk as such:
-  `LLVM_TARGETS := host;NVPTX;AMDGPU;BPF`
-* `] build LLVM` to rebuild LLVM
-* Run `bpfgen(io, license, f, tt)` to generate a BPF kernel with license
-  `license`, from function `f` with input types `tt`. The kernel's object file
-  (ELF format) will be written to `io`.
-* If your kernel is an XDP filter, load it on the appropriate interface with:
-  `ip link set dev myiface xdp obj mybpfkernel.o verbose`. `iproute2` will
-  output some information on your kernel, which is useful for debugging when
-  the Linux kernel refuses to load your kernel (this is common). When you're
-  done with that kernel, unload it with `ip link set dev myiface xdp off`.
+BPFnative provides the ability to write eBPF filters in Julia. Additionally,
+wrappers to the [libbpf](https://github.com/libbpf/libbpf) library are provided
+to make it easy to load eBPF programs into the Linux kernel in for a variety of
+use cases.
