+### Flatpak from terminal
+
+If you want a more pure console use, this script run flatpak version disowning the process and silence the output pushing it to /dev/null.
+Just save the script somewhere in your path, for example `/usr/bin` (or `~/.local/bin` if you have exported it), give execution permissions `chmod +x`, and run `gittyup` from your terminal.
+
+```bash
+#!/bin/bash
+DIR=$(dirname "${BASH_SOURCE[0]}")
+function run_disown() {
+    "$@" & disown
+}
+function run_disown_silence(){
+    run_disown "$@" 1>/dev/null 2>/dev/null
+}
+run_disown_silence flatpak run com.github.Murmele.Gittyup
