+## Tips
+
+- *Portable Mode*: Create an empty file named `portable.ini` in the same directory as the application binary to enable portable mode.
+- *Debug Symbols*: The emulator always tries to load a symbol file at the same time a rom is being loaded. For example, for ```path_to_rom_file.gb``` it tries to load ```path_to_rom_file.sym```. It is also possible to load a symbol file using the GUI or using the CLI.
+- *Command Line Usage*: ```gearboy [rom_file] [symbol_file]```
+- *Mouse Cursor*: Automatically hides when hovering main output window or when Main Menu is disabled.
+- *Boot ROM*: Gearboy can run with or without a Boot ROM. You can optionally load a Boot ROM and enable it.
