+Maiko is the implementation of the Medley Interlisp virtual machine for a

 ## Development Platforms
 
-We are developing on FreeBSD, Linux, macOS, and Solaris currently
-on arm7l, arm64, PowerPC, SPARC, i386, and x86_64 hardware.
+Development has been primarily on macOS, FreeBSD, and Linux, with testing on Solaris and Windows.

+### Building with CMake
+We provide a `CMakeLists.txt` which provides mostly matching build capabilities to the `make` setup.
+CMake options are provided to control the configuration of the Maiko executables:
+* MAIKO\_DISPLAY\_SDL: [OFF], 2, 3 - selects display subsystem SDL of version specified
+* MAIKO\_DISPLAY\_X11: [ON], OFF - selects X11 display subsystem
+* MAIKO\_NETWORK\_TYPE: [NONE], SUN\_DLPI, SUN\_NIT, NETHUB - network subsystem access
+* MAIKO_RELEASE: [351], various - see `maiko/inc/version.h`
+
+While SDL3 is selectable, the Maiko code has not yet been updated to work with the SDL3 API.
 
 ### Building For macOS
 
-* Running on macOS requires an X server, and building on a Mac requires X client libraries.
+* Building/running on macOS requires either an X server and X client libraries or the SDL2 library.
 An X-server for macOS (and X11 client libraries) can be freely obtained at https://www.xquartz.org/releases
-
-### Building for Windows 10
-
-Windows 10 currently requires "Docker for Desktop" or WSL2 and a (Windows X-server).
-See [Medley's README](https://github.com/Interlisp/medley/blob/master/README.md) for more.
