+### Put config in rustdesk.exe file name (Windows only)
+
+Change `rustdesk.exe` to rustdesk-`host=<host-ip-or-name>,key=<public-key-string>`.exe, e.g. rustdesk-`host=192.168.1.137,key=xfdsfsd32=32`.exe. You can see the config result in the About Window below.

+You need to set both `host` and `key`, missing either one will not work.
+
+Optionally add a `,` (comma) character after the key, before the `.exe` part as a delimiter, to avoid the key being mangled if Windows or the browser renames the file when downloading duplicated names.
+
+If there are invalid characters in the key which can not be used in a Windows file name, please remove the
+`id_ed25519` file from your server and restart `hbbs`/`hbbr`. This will cause the `id_ed25519.pub` file to regenerate. You may need to
+repeat this process until you get valid characters.
