 ## Development Platforms

-Development has been primarily on macOS, FreeBSD, and Linux, with testing on Solaris and Windows.
-Processor architectures i386, x86\_64, arm64, arm7l, and SPARC.
+We are developing on FreeBSD, Linux, macOS, and Solaris currently
+on arm7l, arm64, PowerPC, SPARC, i386, and x86_64 hardware.


 ## Building Maiko

-### Building with make
-Building requires a C compiler (`clang` preferred), either `make` or `CMake`, and X11 client libraries (`libx11-dev`), or SDL2. For example, using `make` and X11:

-* The build will (attempt to) detect the OS-type and cpu-type. It will build binaries `lde` and `ldex` in `../`_`ostype.cputype`_ (with .o files in `../`_`ostype.cputype-x`_. For example, Linux on a 64-bit x86 will use `linux.x86_64`, while macOS 11 on a (new M1) Mac will use `darwin.aarch64`.
-* If you prefer `gcc` over `clang`, you will need to edit the makefile fragment for your configuration (`makefile-ostype.cputype-x`) and comment out the line (with a #) that defines `CC` as `clang` and uncomment the line (delete the #) for the line that defines `CC` as `gcc`.
-
-### 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

-* Building/running on macOS requires either an X server and X client libraries or the SDL2 library.
+* Running on macOS requires an X server, and building on a Mac requires X client libraries.
 An X-server for macOS (and X11 client libraries) can be freely obtained at https://www.xquartz.org/releases
-The SDL library is freely available from https://libsdl.org
+
+### Building for Windows 10
+
+Windows 10 currently requires "Docker for Desktop" or WSL2 and a (Windows X-server).
