 puzzle collection. The collection's web site is at
 <https://www.chiark.greenend.org.uk/~sgtatham/puzzles/>.
 
-If you've obtained the source code by downloading a .tar.gz archive
-from the Puzzles web site, you should find several Makefiles in the
-source code. However, if you've checked the source code out from the
-Puzzles git repository, you won't find the Makefiles: they're
-automatically generated by `mkfiles.pl', so run that to create them.
+The puzzle collection is built using CMake <https://cmake.org/>. To
+compile in the simplest way (on any of Linux, Windows or Mac), run
+these commands in the source directory:
 
-The Makefiles include:
-
- - `Makefile.am', together with the static `configure.ac', is intended
-   as input to automake. Run `mkauto.sh' to turn these into a
-   configure script and Makefile.in, after which you can then run
-   `./configure' to create an actual Unix Makefile.
-
- - `Makefile.vc' should work under MS Visual C++ on Windows. Run
-   'nmake /f Makefile.vc' in a Visual Studio command prompt.
-
- - `Makefile.cyg' should work under Cygwin / MinGW. With appropriate
-   tweaks and setting of TOOLPATH, it should work for both compiling
-   on Windows and cross-compiling on Unix.
-
- - `Makefile.osx' should work under Mac OS X, provided the Xcode
-   tools are installed. It builds a single monolithic OS X
-   application capable of running any of the puzzles, or even more
-   than one of them at a time.
-
- - `Makefile.wce' should work under MS eMbedded Visual C++ on
-   Windows and the Pocket PC SDK; it builds Pocket PC binaries.
-
-Many of these Makefiles build a program called `nullgame' in
-addition to the actual game binaries. This program doesn't do
-anything; it's just a template for people to start from when adding
-a new game to the collection, and it's compiled every time to ensure
-that it _does_ compile and link successfully (because otherwise it
-wouldn't be much use as a template). Once it's built, you can run it
-if you really want to (but it's very boring), and then you should
-ignore it.
-
-DO NOT EDIT THE MAKEFILES DIRECTLY, if you plan to send any changes
-back to the maintainer. The makefiles are generated automatically by
-the Perl script `mkfiles.pl' from the file `Recipe' and the various
-.R files. If you need to change the makefiles as part of a patch,
-you should change Recipe, *.R, and/or mkfiles.pl.
