+### gunicorn conf file
+Gunicorn configuration file isn't under version control.
+You need to create a `gunicorn_config.py` like this:
+
+```python
+worker_class = "gevent"
+workers = 1
+bind = "0.0.0.0:5000"
+```
+
+If you need to run the server with ssl cert, add these rows:
+
+```python
+certfile = "/path/to/ssl/certfile.pem"
+keyfile = "path/to/ssl/privkey.pem"
