sudo emerge --sync

If Hyperland is not available in the default repositories, you might need to add a third-party overlay. For example, if it's available on the `hyperland` overlay, you can enable it by adding the following line to `/etc/portage/repos.conf/hyperland.conf`:

   [hyperland]
   location = /var/lib/layman/hyperland
   enabled = yes
   auto-sync = yes
   sync-type = git
   sync-uri = https://github.com/hyperland-org/overlay.git

Then, update your layman overlays:

   sudo layman -S hyperland

Once the repository is enabled, you can install Hyperland using `emerge`:

   sudo emerge --ask x11-wm/hyperland

If you are using a display manager like LightDM or SDDM, ensure it is configured to start Hyperland as the default session.

You can manually start Hyperland by running:

   hyperland

If you encounter any issues during installation or startup, check the logs for errors. The logs are typically located in `/var/log/` and can be viewed using `journalctl` for systemd-based systems.

By following these steps, you should be able to successfully install and run Hyperland on your Gentoo system.
