The demos provided in this repository are provided as "canned demos".

The demos work their way up in terms of complexity and depth of use-cases and are intended to be followed in the order that is shown below:

Level	Description
001-basic	Basic nornir filtering using one-dimensional filters
002-intermediate	Intermediate nornir filtering using multi-dimensional filters
