 This means that Vim will search for the MzScheme DLL files only when needed.
 When you don't use the MzScheme interface you don't need them, thus you can
 use Vim without these DLL files.
+NOTE: Newer version of MzScheme (Racket) require earlier (trampolined)
+initialisation via scheme_main_setup.  So Vim always loads the MzScheme DLL at
+startup if possible.
 
 To use the MzScheme interface the MzScheme DLLs must be in your search path.

+2) Building with Racket support
+
+MzScheme and PLT Scheme names have been rebranded as Racket.  Vim with Racket
+(https://racket-lang.org/) support can be built with either MSVC or MinGW (or
+Cygwin).
+
+You need to set the following variables:
+
+    MZSCHEME:          Where Racket is installed.
+                       E.g. C:\Program Files (x86)\Racket
+    DYNAMIC_MZSCHEME:  Whether dynamic linking is used. Usually, set to yes.
+    MZSCHEME_VER:      Racket DLL version. E.g. 3m_9z0ds0 for Racket 6.3.
+    MZSCHEME_COLLECTS: (Optional) Path of the collects directory used at
+                       runtime. Default: $(MZSCHEME)\collects
+                       User can override this with the PLTCOLLECTS environment
+                       variable.
+
+E.g. When using MSVC (as one line):
+
+    nmake -f Make_mvc.mak
+        MZSCHEME="C:\Program Files (x86)\Racket" DYNAMIC_MZSCHEME=yes
+        MZSCHEME_VER=3m_9z0ds0
+
+Or when using MinGW (as one line):
+
+    mingw32-make -f Make_ming.mak
+        MZSCHEME='C:/Program\ Files\ (x86)/Racket' DYNAMIC_MZSCHEME=yes
+        MZSCHEME_VER=3m_9z0ds0

+Vim with Lua support can be built with either MSVC or MinGW (or maybe Cygwin).
+You can use binaries from LuaBinaries: http://luabinaries.sourceforge.net/
+This also applies to when you get a Vim executable and don't build yourself,
+do the part up to "Build".
 
 1) Download and install LuaBinaries
+
 Go to the Download page of LuaBinaries:
-    http://luabinaries.sourceforge.net/download.html
+  http://luabinaries.sourceforge.net/download.html
 
 Download lua-X.Y.Z_Win32_dllw4_lib.zip for x86 or
-lua-X.Y.Z_Win64_dllw4_lib.zip for x64.  You can use them for both MSVC and
+lua-X.Y.Z_Win64_dllw4_lib.zip for x64.  You can use them both for MSVC and
 MinGW.
 
 Unpack it to a working directory. E.g. C:\projects\lua53.
 Lua's header files will be installed under the include directory.
 
+Copy luaXY.dll to your Windows system directory. The system directory depends
+on your Windows bitness and Vim bitness:
+  32-bit Vim on 32-bit Windows: C:\Windows\System32
+  32-bit Vim on 64-bit Windows: C:\Windows\SysWOW64
+  64-bit Vim on 64-bit Windows: C:\Windows\System32
+
+Or another option is copying luaXY.dll to the directory where gvim.exe
+(or vim.exe) is.
+
 
 2) Build
-You need to set the following variables:
 
-    LUA:         Where Lua is installed. E.g. C:\projects\lua53.
