Documentation update to provide guidelines to use this library in production

[MacNale]

Is your feature request related to a problem? Please describe. I am interested in using this library for anomaly detection and forecast for the metrics collected for our systems and applications. I dont know, how can I use this library in production.

Describe the solution you'd like Documentation on using the library at scale with an example would be much helpful.

1. How to build the model
2. How to score the incoming metrics for anomaly detection in near real time
3. How to retrain the model
4. How to evaluate the performance in production

Describe alternatives you've considered None

Additional context None
