60

61
+ ### How To Convert Your WordPress Website Into A Progressive Web App
62
+
63
+ #### WordPress Installation
64
+
65
+ * Visit WordPress Admin > Plugins > Add New
66
+ * Search for 'Super Progressive Web Apps'
67
+ * Click "Install Now" and then "Activate" Super Progressive Web Apps
68
+
69
+ To install manually:
70
+
71
+ * Upload super-progressive-web-apps folder to the /wp-content/plugins/ directory on your server
72
+ * Go to WordPress Admin > Plugins
73
+ * Activate Super Progressive Web Apps plugin from the list.
74
 
75
+ #### Customizing Your Progressive Web App
76
+
77
+ Your Progressive Web App should be ready to test with the default settings upon activation. You can customize it further and make it truly your own.
78
+
79
+ * Go to WordPress Admin > Settings > SuperPWA
80
+ * Set a Background Color for the splash screen to be shown when your PWA is opened on a mobile device.
81
+ * Set the Application Icon. This will be the icon of your PWA when it is added to the homescreen in a mobile device. The icon must be a PNG image and exactly 192 x 192 pixels in size.
82
+ * Set the Offline Page. This page will be displayed if the user is offline and the page he requested is not cached already. Ideally you should create a dedicated WordPress page and set it here. Within the page you create, you could add a note that reads, "It looks like you are offline and the page you requested is not available right now. Please check back again once you are online.".
83
+ * Click "Save Settings".
84
+
85
+ #### Testing Your Progressive Web App
86
+
87
+ * Open a supported browser in a supported device (for eg: Chrome for Android (62 or higher) in an Android Phone)
88
+ * Enter your website and wait till it fully loads
89
+ * You should see a pop-up that has your Application Icon and a button that reads "ADD TO HOME SCREEN".
90
+ * Click on it and your PWA will be added to your home screen. Wait for the install to complete.
91
+ * Go to your home screen and open your PWA. Browse into a few pages if you like. Close the App.
92
+ * Disconnect from the internet and now open your PWA again. You should be able to see all the pages that you previously browsed.
93
+ * Try visiting a page that you did not visit before. You should see the page you set as your "Offline Page" in the settings of SuperPWA.
94
+
95
+ #### Troubleshooting Your Progressive Web App
96
+
97
+ Uh, oh. Your PWA did not work as expected? You do not see the "Add to Home Screen" notice?
98
+
99
+ * Make sure your website has a SSL certificate installed. i.e. your website should be https instead of http (as in https://your-domain.com).
100
+ * Make sure you are using a supported device and a supported browser. Refer to the "Device and Browser Support For PWA" list above.
101
+ * Clear the browser cache and try again. In Chrome for Android, go to Settings > Privacy > "Clear browsing data".
102
+ * If the application icon does not update after first install, delete the PWA from your phone, clear browser cache and install again. (We are working on making it better.)
103
+ * Create a [new support ticket](https://wordpress.org/support/plugin/super-progressive-web-apps) and share a link to your website. We will take a look and figure it out for you.
