-      1) Finishing the installation
-
-        To globally install the layout, you need to manually link the layout bundle (only once):
-          sudo ln -sf '#{prefix}/qwerty-fr.bundle' '/Library/Keyboard Layouts/'
+  url "https://github.com/qwerty-fr/qwerty-fr/releases/download/v#{version}/qwerty-fr_#{version}_mac.zip",
+      verified: "github.com/qwerty-fr/qwerty-fr/"
+  name "qwerty-fr keyboard layout"
+  desc "QWERTY-based layout. Type EU languages, greek, math, currencies, & more!"
+  homepage "https://qwerty-fr.org/"
 
-        If you only want to only install the layout for the current user, do the following instead:
-          ln -sf '#{prefix}/qwerty-fr.bundle' '~/Library/Keyboard Layouts/'
+  depends_on macos: ">= :sierra"
 
+  artifact "qwerty-fr.bundle", target: "/Library/Keyboard Layouts/qwerty-fr.bundle"
 
-      2) Restart your system (dead keys don't work properly before restarting).
-
-
-      3) You can then enable the qwerty-fr layout by doing the following:
-          a) Open "System Preferences" → "Keyboard" → "Input Source".
-          b) Click on "+" → Search for "qwerty-fr" → Click on "Add".
-          c) Click on the layout selection icon in the menu bar of macOS and choose "qwerty-fr"
