# Helium Browser flags for hardware video decoding on Wayland and for colors that match KDE apps. From the repository root: ```sh stow -d kde -t "$HOME" helium ``` Helium takes its colors and window buttons from GTK. In Settings → Appearance, set Theme to GTK and turn off "Use system title bar and borders". With the KDE `theme` package applied, GTK follows the Darwin Breeze colors and the window buttons match KWin's; see [Darwin Breeze → Helium notes](../theme/README.md#helium-notes).
