+## Usage
+
+Dokodemo-door can be used as Transparent proxy (in the next section) and can be used to mapping a port.
+
+Some services does not support proxy likes SOCKS5, but using Tun or Tproxy could be too complicated. If these services only communicate with only one port (like iperf, Minecraft server, Wireguard endpoint, etc.), dokodemo-door can be used.
+
+Below is an example config (if the default outbound is an effective proxy):
+
+```json
+{
+  "listen": "127.0.0.1",
+  "port": 25565,
+  "protocol": "dokodemo-door",
+  "settings": {
+    "address": "mc.hypixel.net",
+    "port": 25565,
+    "network": "tcp",
+    "followRedirect": false,
+    "userLevel": 0
+  },
+  "tag": "mc"
+}
+```
+
+The core will listen at `127.0.0.1:25565`, and the traffic coming in through this inbound will be send to `mc.hypixel.net:25565` (a Minecraft server) through the default outbound. Then you can connect the Minecraft client to the Hypixel server through the proxy by set the game server to `127.0.0.1:25565` in the Minecraft client.
