+## Wayland
+On BSD and Linux systems, you may want to build an executable for Wayland only, meaning it will not run through XWayland. This will increase performance and also allow drag-on-drop functionality. Most Wayland setups can run X11 apps, but no X11 setup can run Wayland apps. Because of this, all executables are shipped for use with X11. This may change in the future, but if you want to build for Wayland, it's as simple as the commands above, but just adding a `wayland` tag to the build command.
+
+A Wayland-only executable will also substantially decrease the level of screen tearing and lag.

+```bash
+git clone https://github.com/sunglocto/pi-im
+cd pi-im
+go mod tidy
+go build -tags wayland .
+./pi-im
