+Note that for microcontroller development you must flash your hardware devices 
+from your host environment, since you cannot run ``tinygo flash`` from inside 
+the docker container.
+
+So your workflow could be:
+
+- Compile TinyGo code using the Docker container into a HEX file.
+- Flash the HEX file from your host environment to the target microcontroller.
