+# Window Position (window-pos)
+
+A small native library to get the size and position of a window on windows.
+
+## Installing
+
+```
+npm install git+https://github.com/Soundofdarkness/window-pos.git
+```
+
+## Usage
+
+```js
+const windowPos = require("window-pos");
+
+// Rect: {top: 0, bottom: 0, left: 0, right: 0} or null if the window is not found.
+const rect = windowPos.getWindowCoords("Window Title");
+
+// Size: {width: 0, height: 0}
+const size = windowPos.getWindowSize("Window Title")
+```
