-It is recommended to Build Robot Code at least once when connected to the Internet before heading to an area where Internet connectivity is limited (for example, a competition). This ensures that the relevant files are downloaded to your filesystem.
+The Dependency Manager will automatically build your program when it loses focus. This allows you to use the changed dependencies.
