@@ -34,6 +34,18 @@ to build the "126" configuration of the "SCZ180" platform:
 
 	make ROM_PLATFORM=SCZ180 ROM_CONFIG=126
 
+Please be aware that the make-based build does have a couple of
+deficiencies.
+
+First, there are some build failures that will not stop the make 
+process.  Some of this is because real CP/M 2.2 tools are used in 
+places and CP/M 2.2 does not allow programs to return a result code.
+
+Second, not all dependencies are properly handled.  So, changes to some
+files will not cause things to rebuild as appropriate.  In general, I
+recommend doing a "make clean" before running "make" to ensure that
+everything is fully rebuilt.

 For macOS users, you may encounter a failure reading or writing files.
 This is caused by protection features in macOS (at least, in Catalina)
 that prevent programs built on your local system (unsigned) from
