+Make sure You have the path to the i3switch binary in Your `$PATH`. You can check this by running:
+
+```bash
+which i3switch
+```

+Then modify Your i3 config file to bind the commands to keybindings. For example:
+
+```
+bindsym $mod+h exec i3switch left
+bindsym $mod+j exec i3switch down
+bindsym $mod+k exec i3switch up
+bindsym $mod+l exec i3switch right
+bindsym $mod+Tab exec i3switch next wrap
+bindsym $mod+Shift+Tab exec i3switch prev wrap
+```
