 I made this for my [GPD MicroPC][2], which has a very nice qwerty keyboard for
 thumb typing but no touch screen.
 
+# Install

+```sh
+go install go.imnhan.com/iwpick@latest

+It makes a couple of assumptions:
+
+- You have the `iwctl` executable in your $PATH and the necessary permission to
+  run it. For Arch that means being in the appropriate usergroup(s).
+- Your wireless device is `wlan0`. Otherwise, pull this repo, update the
+  WIFI_DEVICE const and run `make` to recompile. Bonus points if you make it a
+  [flag][3] and send me a pull request :^)
