+# ZeroMQ interface for OpenAI Gym
+
+This library adds a ZeroMQ interface for the [OpenAI Gym Project](https://github.com/openai/gym). This implementation runs faster than my previous [HTTP interface](https://github.com/Brandon-Rozek/GymHTTP)!
+
+Why would I want to do this? If you want to decouple the processing of 
+the environment from the training of your models this might be 
+beneficial.
+
+To start the webserver
+
+```bash
+python gymserver.py port_num
+```
+
+Then in your main application
+
+```python
+from gymclient import Environment
+env = Environment("127.0.0.1", 5000)
+```
