+1. INTRODUCTION
+---------------
+* Show a message in a Responsive Popup for your first time users. The module doesn't require any JavaScript library but
+  uses pure JavaScript to show a nice Popup.
+* The module stores the browser cookie information about the user so the popup is displayed only once, first time the
+  user visits your website.
+
+2. INSTALLATION
+---------------
+* Install as you would normally install a contributed Drupal module. See:
+  https://www.drupal.org/docs/8/extending-drupal-8/installing-contributed-modules-find-import-enable-configure-drupal-8
+  for further information.
+
+3. Usage:
+---------
+  * Once the module is installed, go to '/admin/config/popup_dialog/popupsettings'.
+  * When enable checkbox is checked, users will be getting the Popup based on cookie.
+  * Custom Content, Blocks, Views options is there in Category Settings.
+  * You can select existing blocks or views or can create custom content to show in the popup.
+  * Delay amount is the time lag after which the popup will be shown to the user.
+  * Top Offset is the vertical spacing of the popup from top.
