 # 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.

+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.
 
 ## For developers
@@ -45,7 +61,6 @@ This repository contains:
 - ``nac3parser``: Python parser (based on RustPython).
 - ``nac3core``: Core compiler library, containing type-checking and code generation.
 - ``nac3standalone``: Standalone compiler tool (core language only).
-- ``nac3ld``: Minimalist RISC-V and ARM linker.
 - ``nac3artiq``: Integration with ARTIQ and implementation of ARTIQ-specific extensions to the core language.
 - ``runkernel``: Simple program that runs compiled ARTIQ kernels on the host and displays RTIO operations. Useful for testing without hardware.
