Thanks Tapobrata.

Sure, here are two articles on good product documentation:

- 12 Best Examples of Product Documentation and Help Guides (https://documentor.in/2148/best-examples-product-documentation-guides/)

- This is How to Build the Best User Documentation (https://www.techsmith.com/blog/user-documentation/)

And here's a nice article with best practices and examples of guided product onboarding (User onboarding: 11 best practices and 15 examples)

Hope these help!
