+## Trojan-Go Docker Image by Teddysun
+
+[Trojan-Go][1] is An unidentifiable mechanism that helps you bypass [GFW](https://en.wikipedia.org/wiki/Great_Firewall).
+
+Trojan-Go features multiple protocols over `TLS` to avoid both active/passive detections and ISP `QoS` limitations.
+
+Docker images are built for quick deployment in various computing cloud providers.
+
+For more information on docker and containerization technologies, refer to [official document][2].
+
+## Prepare the host
+
+If you need to install docker by yourself, follow the [official installation guide][3].
+
+## Pull the image
+
+```bash
+$ docker pull teddysun/trojan-go
+```
+
+This pulls the latest release of trojan-go.
+
+It can be found at [Docker Hub][4].
+
+## Start a container
+
+You **must create a configuration file**  `/etc/trojan-go/config.json` in host at first:
+
+```
+$ mkdir -p /etc/trojan-go
+```
+
+A sample in JSON like below:
+
+```
+{
+    "run_type": "server",
+    "local_addr": "0.0.0.0",
+    "local_port": 443,
+    "remote_addr": "127.0.0.1",
+    "remote_port": 80,
+    "password": [
+        "your_awesome_password"
+    ],
+    "ssl": {
+        "cert": "server.crt",
+        "key": "server.key",
+        "sni": "your-domain-name.com",
+        "fallback_port": 1234
+    }
+}
+```
+
+An online documentation can be found [here](https://p4gefau1t.github.io/trojan-go/basic/config/)
+
+There is an example to start a container that listen on port `443`, run as a Trojan server like below:
+
+```bash
+$ docker run -d --network host --name trojan-go --restart=always -v /etc/trojan-go:/etc/trojan-go teddysun/trojan-go
+```
