Add documents for new commands and their use cases with examples

[Harsh4902]

Describe the bug

• Currently we have only README.md for documentation.
• We can improve README.md with detailed installation description.
• We can add detailed documentation for new commands with examples, which will be really helpful for the new users.

Attach any resources that can help us understand the issue.
