+## Apply necessary useflags

+
+## Unmask dependencies and xdph
+### /etc/portage/package.accept_keywords
+```plain
+gui-libs/xdg-desktop-portal-hyprland **

+=dev-qt/qtwayland-6.4.0
+=dev-qt/qtdeclarative-6.4.0
+=dev-qt/qtshadertools-6.4.0
+```
+
+btw those are the useflags that I have tested, you could also test others. Also if the gentoo devs update the qt ebuilds without marking them as stable you'll need to check the ebuild version and update it on '/etc/portage/package.accept_keywords' and '/etc/portage/profile/package.unmask'
+
+example: '=dev-qt/qtbase-6.5.0'
+

 It's recommended to uninstall any other portal implementations to avoid conflicts with the `-hyprland` or `-wlr` ones.
