 Go to http://localhost:1337 to upload files.
 
 Files will be uploaded to ./uploads
 
 Upload limit size: 10000MB
+
+## Usage as PWA (Progressive Web App)
+
+After initial start you find the root ca certificate in the uploads folder. Install it on your device to trust the self signed certificates for the local ip defined by the `HOSTIP` environment variable.
+After that you can install the webapp as PWA on your device. You may need to reload the page after the certificate is installed.
+
+A PWA can only be installed via https. So please open the webapp via https://localhost:1337 after installing the ca certificate.
+
+**Advantage**: You can directly share files from your native share menu on the device to the webapp.
