 Phoenix supports the following (case sensitive) preferences:
 
 - `daemon` (boolean): if set `true` Phoenix will run completely in the background, this also removes the status bar menu, defaults to `false`
+- `openAtLogin` (boolean): if set `true` Phoenix will automatically open at login, defaults to `false`
 
 Set the preferences using the `Phoenix`-object — for example:
 
 ```javascript
-Phoenix.set({ 'daemon': true });
+Phoenix.set({
+
+    'daemon': true,
+    'openAtLogin': true
+
+});
 ```
