Hey @Akshat005Chaudhary, thanks for adding the quickstart—really appreciate the effort. Could you please include a short video showcasing your changes?

Also, please avoid making changes to the sidebar. I noticed updates to the test coverage integration as well—kindly avoid including unnecessary changes.

Additionally, please include the Keploy record and replay commands, making sure the commands are clearly visible. It would be great to have these commands documented for both Docker-based and non-Docker setups. Thanks
