## Resolution
## Installation instructions
`cabal run exe:MetaBrush` will build and launch the application.
You will need certain C libraries to be installed on your system and recognised
by `pkg-config`. See the [Install guide](installation_notes.md) for more information, or use the provided `shell.nix` Nix file (NB: not necessarily up-to-date).
## Tips and tricks
### Change UI size
To increase or decrease the size of the UI, set the `GDK_SCALE` environment
variable. The current default is `setenv GDK_SCALE=2`.
### Theming
You can customise the theme by editing `theme.css`.
There isn't (yet) a way to switch between themes in the UI; you will need to
relaunch the application for changes to take effect.
