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
