 dotool reads commands from stdin and simulates keyboard and mouse events.
 It works everywhere on Linux, including in X11, Wayland and TTYs.
 
-It takes about half a second to register the virtual device, but it can be
-kept using the daemon.
-
 ## Install From Source
 
-With go (>=1.19) run:
+With `go` installed, run:
 
     sudo ./install.sh
 
+## Permission
+
+dotool requires permission to `/dev/uinput` to create the virtual input
+devices, and a udev rule grants this to users in group input.
+
+You could try:
+
+    echo type hello | dotool
+
+and if need be, you can run:
+
+    sudo groupadd -f input
+    sudo usermod -a -G input $USER
+
+and re-login and trigger the udev rule or just reboot.
+
 ## Usage
 
-dotool will require root permissions unless you are in group input.

-The daemon and client, `dotoold` and `dotoolc`, can used to keep a persistent
