 ## How to use launcher
 
-Assuming https://github.com/kennylevinsen/dot-desktop is installed: `eval "$(dot-desktop "$(dot-desktop | wldash)")"`
+The launcher for wldash is built-in, based on https://github.com/kennylevinsen/dot-desktop. Pluggable systems may come back in the future.
 
-wldash simply takes a new-line separated list of strings, and returns the selection. dot-desktop generates this list, and afterwards processes the selection to return the proper instantiation string. Eval then executes it.

+- WLDASH_APP_OPENER: The command used to open normal applications. For sway, the recommended value is "swaymsg exec".
+- WLDASH_TERM_OPENER: The command used to open terminal applications.
