+
+## How It Works
+1. Rent a VPS located outside your country.
+2. Point a domain to your server’s IP address: buy one or use a [free option](https://www.duckdns.org/).
+3. Launch NaiveGUI, enter your domain name, username, and password, then click “Create Client and Server”.
+Save the generated archive containing:
+- **client.json** — client configuration
+- **Caddyfile** — server configuration
+4. Install the `caddy-forwardproxy-naive` package on your server.
+**Important:** this package includes `/etc/caddy` and provides a full web server. It is intended to be the only web server running on your VPS.
+5. Upload the `Caddyfile` to the server into `/etc/caddy` and start the service:
+```
+systemctl restart caddy
+```
+6. In NaiveGUI, verify that your server is reachable over HTTPS using the **"Check page…"** link.
+7. If the domain is accessible, click **"Start"** and verify your proxy [using this test](https://whoer.net/ru).
+---
+### Connection Modes
+
+The client and server support two modes: **QUIC** and **HTTPS (TCP)**.  
+  
+In some regions, QUIC may be blocked or unstable, so **HTTPS is usually the preferred option**.  
+  
+You can test the connection speed in each mode using the **"Check connection speed…"** link in NaiveGUI.
