+
+Share your VPN connection over hotspot or repeater. (root required)
+
+## Q & A
+
+### Can I use the repeater feature without enabling VPN?
+
+This app is designed for VPN interface as upstreams to simplify handling of connection change and NAT issues.
+You could use stub VPN apps like [Adguard](https://github.com/AdguardTeam/AdguardForAndroid)
+together with this app as a workaround.
+
+### Can I use this app without root?
+
+Without root, you can only:
+
+* View connected devices for system tethering and monitor them if your SELinux status is not enforcing
+  (otherwise you can still do manual refreshes);
+* Play around with settings.
