+We normally suggest using the most recent ("HEAD") Pistache version.

+Building Pistache from Source on macOS
+======================================
+
+If you prefer not to install with brew, Pistache can be built from
+source.
+
+Install the necessary brew packages via terminal command line:
   brew install meson
   brew install doxygen
   brew install googletest (skip this if installing with gcc - see later)

+
+
+Troubleshooting brew install on Intel Macs
+------------------------------------------
+
+On some Intel-based MACs, when installing Pistache with brew you may
+see errors like:
+    ==> meson setup build ...
+    Traceback (most recent call last):
+      File "/usr/local/opt/meson/bin/meson", line 5, in <module>
+        from mesonbuild.mesonmain import main
+    ModuleNotFoundError: No module named 'mesonbuild'
+    ...
+    Error: Testing requires the latest version of pistache
+
+This a problem installing Python3, a dependency of meson. We found it
+could be fixed by:
+  sudo mkdir /usr/local/Frameworks
+  sudo chown <your-user-name> /usr/local/Frameworks
+  (Substituting your own macOS username for <your-user-name>)
+NB: This applies solely to Intel-based Macs. Homebrew uses a different
+location for files on Apple-silicon("M")/Arm-based MACs.
+
+
+Building with GCC
+-----------------
+
+By default, Pistache on macOS builds with clang, which is the default
+Apple compiler. If you prefer to use gcc, you can utilize the
+gccmacsetup.sh script provided by Pistache before doing the build,
+like this:
+  source bldscripts/gccmacsetup.sh
+  bldscripts/mesbuild.sh
+  bldscripts/mestest.sh
+  bldscripts/mesinstall.sh
+
+
+Convenience Scripts
+-------------------
+
+The following scripts cna be used in any environment except
+Windows. The meaning of each convenience script is as follows:
+  mesbuild.sh - build release version
+  mestest.sh - test release version
+  mesinstall.sh - install release version
 
-  mesbuilddebug.sh - build debug version using meson
+  mesbuilddebug.sh - build debug version
   mestestdebug.sh - test debug version with meson
-  mesinstalldebug.sh - install debug version using meson
+  mesinstalldebug.sh - install debug version
 
-  mesbuildflibev.sh - build version using meson forcing libevnet use
-  mestestflibev.sh - test version using meson with libevnet use
-  mesinstallflibev.sh - install version using meson with libevnet use
+Linux-only scripts. Note - all environments except Linux use libevent
+by default. libevent is optional on Linux:
+  mesbuildflibev.sh - build version forcing libevent use
+  mestestflibev.sh - test version with libevent use
+  mesinstallflibev.sh - install version with libevent use
 
-  mesbuildflibevdebug.sh - build debug ver using meson forcing libevnet use
-  mestestflibevdebug.sh - test debug ver using meson with libevnet use
-  mesinstallflibevdebug.sh - install debug ver using meson with libevnet use
+  mesbuildflibevdebug.sh - build debug version forcing libevent use
+  mestestflibevdebug.sh - test debug version with libevent use
+  mesinstallflibevdebug.sh - install debug version with libevent use
 
+Also:
   clean.sh - remove build directories
+  gccmacsetup.sh - configure for GCC build on macOS
