 ## System Resource Monitoring
 
 ### Glances
-
 The easiest method for displaying system info and resource usage in Dashy is with [Glances](https://nicolargo.github.io/glances/).
 
 Glances is a cross-platform monitoring tool developed by [@nicolargo](https://github.com/nicolargo). It's similar to top/htop but with a [Rest API](https://glances.readthedocs.io/en/latest/api.html) and many [data exporters](https://glances.readthedocs.io/en/latest/gw/index.html) available. Under the hood, it uses [psutil](https://github.com/giampaolo/psutil) for retrieving system info.
