+## KMS Server Docker Image by Teddysun
+
+This is A fully Microsoft compatible KMS server with Docker Image.
+vlmcsd is a fully Microsoft compatible KMS server that provides product activation services to clients.It is meant as a drop-in replacement for a Microsoft KMS server (Windows computer with KMS key entered).It currently supports KMS protocol versions 4, 5 and 6.
+vlmcsd is designed to run on POSIX compatible operating systens. It only requires a basic C library with a BSD-style sockets API and either `fork` or `pthreads`. That allows it to run on most embedded systems like routers, NASes, mobile phones, tablets, TVs, settop boxes, etc. Some efforts have been made that it also runs on Windows.
+
+Docker images are built for quick deployment in various computing cloud providers.
+For more information on docker and containerization technologies, refer to [official document][1].
+
+## Prepare the host
+
+If you need to install docker by yourself, follow the [official installation guide][2].
+
+## Pull the image
+
+```bash
+$ docker pull teddysun/kms
+```
+
+This pulls the latest release of shadowsocks-libev.
+It can be found at [Docker Hub][3].
+
+## Start a container
+
+```bash
+$ docker run -d -p 1688:1688 --name kms teddysun/kms
+```
+
+**Note**: The TCP port number `1688` must be opened in firewall.
