+If using wayland you will need to have [wl-clipboard](https://github.com/bugaevc/wl-clipboard) installed, for the `wl-copy` command.

+If you are not using GNOME/KDE/Qtile/Sway, and are using something like a wlroots-based compositor (ex. [Hyprland](https://github.com/hyprwm/Hyprland/), [River](https://github.com/riverwm/river), etc), you will need to set the `XDG_CURRENT_DESKTOP` environment variable to `sway`, which will just override it for this script. Adding `export XDG_CURRENT_DESKTOP=sway` to the start of the script will work.

+After this, replace the `xsel -ib` with `wl-copy` in the script.

 You can either use the script below, or generate one directly from Zipline (just like how you can generate a ShareX config).
 To upload files using flameshot we will use a script. Replace $TOKEN and $HOST with your own values, you probably know how to do this if you use linux.
