 ## Compiling the application
 
+The master branch is for daily development and it uses the latest mbed-os/master.
+
+To use the latest stable version update to a Mbed OS release tag, for example:
+
+```
+mbed releases
+ * mbed-os-5.10.4
+   ...
+mbed update mbed-os-5.10.4
+```
+
+You may need to use `--clean` option to discard your local changes (use with caution).
