- If you are not seeing anything in the terminal check that a theme has been set. If there is no theme, everything will be drawn in black by default. A default theme can be found in the [themes directory](../../themes).
- If the terminal isn't responding to keyboard or mouse input check that `focus_mode` is set to `All`, otherwise `_gui_input()` won't be called so no input will be processed.
- If you want to customize the colors and font of the terminal, be sure to set the theme property. A default theme that can be found in the [themes directory](../../themes) and can be used as a template for creating a custom theme.
