+### fzf as dmenu replacement
+
+Why? ...Because it's faster.
+
+So you'll need:
+
+1. terminal that launches fast and supports custom class or window name. [St](https://st.suckless.org/) fits the bill perfectly.
+
+2. window manager with an option to automatically put windows in center based on class or name. Most seem to have it.
+
+
+```sh
+#!/usr/bin/env sh
+# fzfmenu - fzf as dmenu replacement
+
+input=$(mktemp -u --suffix .fzfmenu.input)
+output=$(mktemp -u --suffix .fzfmenu.output)
+mkfifo $input
+mkfifo $output
+chmod 600 $input $output
+
+# it's better to use st here (starts a lot faster than pretty much everything else)
+st -c fzfmenu -n fzfmenu -e sh -c "cat $input | fzf | tee $output" & disown
+
+# handle ctrl+c outside child terminal window
+trap "kill $! 2>/dev/null" EXIT
+
+cat > $input
+cat $output
+rm -f $input $output
+```
+
+Don't forget to add a float/center rule for `fzfmenu` class/name to your wm's config.
