+## Example Usage
+
+ttyd starts web server at port `7681` by default, you can use the `-p` option to change it, the `command` will be started with `arguments` as options. For example, run:
 
 ```bash
-ttyd bash
+ttyd -p 8080 bash -x
 ```
-Then open <http://localhost:7681>, now you can see and control the `bash` console on your web broswer! :tada: 
+Then open <http://localhost:8080> with a broswer, you will get a bash shell with debug mode enabled.
 
-> **TIP:** You may replace `bash` with `login` to get a login prompt first.
+**More Examples:**
+
+- If you want to login with your system accounts on the web broswer, run `ttyd login`.
+- You can even run a none shell command like vim, try: `ttyd vim`, the web broswer will show you a vim editor.
+- Sharing single process with multiple clients: `ttyd tmux new -A -s ttyd vim`, run `tmux new -A -s ttyd` to connect to the tmux session from terminal.
+
+## Docker and ttyd
+
+Docker containers are jailed environments which are more secure, this is useful for protecting the host system, you may use ttyd with docker like this:
+
+- Sharing single docker container with multiple clients: `docker run -it --rm -p 7681:7681 tsl0922/ttyd`.
+- Creating new docker container for each client: `ttyd docker run -it --rm ubuntu`.
