+# NAC3
 NAC3 is a major, backward-incompatible rewrite of the compiler for the [ARTIQ](https://m-labs.hk/artiq) physics experiment control and data acquisition system. It features greatly improved compilation speeds, a much better type system, and more predictable and transparent operation.
 
 NAC3 has a modular design and its applicability reaches beyond ARTIQ. The ``nac3core`` module does not contain anything specific to ARTIQ, and can be used in any project that requires compiling Python to machine code.
@@ -16,40 +21,28 @@ NAC3 is packaged using the [Nix](https://nixos.org) Flakes system. Install Nix 2
 
 After setting up Nix as above, use ``nix shell git+https://github.com/m-labs/artiq.git?ref=nac3`` to get a shell with the NAC3 version of ARTIQ. See the ``examples`` directory in ARTIQ (``nac3`` Git branch) for some samples of NAC3 kernel code.

-Locate a recent build of ``nac3artiq-msys2`` from [Hydra](https://nixbld.m-labs.hk) and download ``nac3artiq.zip``. Then extract the contents in the appropriate location:
+Then run the following commands:
 ```
-pacman -S unzip

-wget https://nixbld.m-labs.hk/build/97899/download/1/nac3artiq.zip  # edit the build number
+pacman -S mingw-w64-x86_64-artiq
-unzip nac3artiq.zip -d C:/msys64/mingw64/lib/python3.9/site-packages

-Install additional NAC3 dependencies:
+Install ``lld-msys2`` manually:
 ```
-pacman -S mingw-w64-x86_64-lld
+wget https://nixbld.m-labs.hk/build/115527/download/1/ld.lld.exe
+mv ld.lld.exe C:/msys64/mingw64/bin
 ```
 
-And you should be good to go.
+Note: This build of NAC3 cannot be used with Anaconda Python nor the python.org binaries for Windows. Those Python versions are compiled with Visual Studio (MSVC) and their ABI is incompatible with the GNU ABI used in this build. We have no plans to support Visual Studio nor the MSVC ABI. If you need a MSVC build, please install the requisite bloated spyware from Microsoft and compile NAC3 yourself.
