This is the README accompanying the source code to Simon Tatham's puzzle collection. The collection's web site is at https://www.chiark.greenend.org.uk/~sgtatham/puzzles/.

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:

cmake . cmake --build .

The manual is provided in Windows Help format for the Windows build; in text format for anyone who needs it; and in HTML for the Mac OS X application and for the web site. It is generated from a Halibut source file (puzzles.but), which is the preferred form for modification. To generate the manual in other formats, rebuild it, or learn about Halibut, visit the Halibut website at https://www.chiark.greenend.org.uk/~sgtatham/halibut/.
