+Debugging
+=========
+
+You can uncomment the '#define DEBUG_MENU' line to add some diagnostic menu
+options for capturing or dumping the capture buffer.
+You can uncomment the '#define DEBUG' and '#define DEBUG_MENU' for a couple
+extra menu options and logging of the received commands.  The DEBUG option
+is generally only useful for development, while the DEBUG_MENU option is
+good for troubleshooting when the logic_analyzer sketch isn't working for you.
+Both are disabled by default to conserve RAM for improved stability.
+
+CLI compiling
+=============
+
+If you want to use the 'arduino-mk' package (on Debian for example ) to compile
+this using the Makefile, you'll need to make a couple of changes since the
+Makefile only supports a single .ino file.  Basically you just need to append
+the other two files to the main .ino and then remove them.
+
+$ cat logic_analyzer_inline_4mhz.ino >> logic_analyzer.ino
+$ cat logic_analyzer_inline_2mhz.ino >> logic_analyzer.ino
+$ rm logic_analyzer_inline_4mhz.ino logic_analyzer_inline_2mhz.ino
+$ make
+
+This will make GIT unhappy so if you need to revert it to run 'git pull' do
+this:
+$ git reset --hard origin/master
