+# Building
+
+Building requires cmake, make, an "arm-none-eabi" toolchain (including
+newlib), and picotool (including the .cmake files;
+eg. /usr/lib/cmake/picotool/*.cmake).
+
+At the time of this writing, on Parabola GNU/Linux-libre that means:
+
+ - make 4.4.1-2
+ - cmake 3.30.3-1
+ - arm-none-eabi-binutils 2.42-1
+ - arm-none-eabi-gcc 14.1.0-1
+ - arm-none-eabi-newlib 4.4.0.20231231-1
+ - picotool 2.0.0-2
