 # Basalt Meter
 
 Work in progress.
+
+## Warning
+
+We order that you MUST make sure that the architecture of your built Presenter is same as the architecture of the Python running Trainer.
+For example, if you build Presenter on Windows x64, you MUST make sure that the Python is also Windows x64.
+The reason is that some data types used by these 2 programs are platform dependent.
