 ## Setting config on remote servers
 
 We make use of excellent [Fabric] to acomplish this. Add a config task to your local fabfile, `dotenv_path` is the location of the absolute path of `.env` file on the remote server.
 
 [Fabric]: http://www.fabfile.org/
 
-```
+```python
 # fabfile.py
 
 from fabric.api import task, run, env
