There are some config you need to change in below files
```
./run.sh
./config.js
./public/js/common.js
```
You can use SSL to encrypt your site by passing certificate path in the `config.js` and set `usessl=true`.
And there is a script called `run.sh`, it's for someone like me to run the server via npm package `forever`, and can passing environment variable to the server, like heroku does.
To install `forever`, just type `npm install forever -g`
