How to submit contributions to quartz

[pratikrath126]

Hey! It's great to see someone interested in adding a new database dialect. To move this forward, the usual path is to open a pull request against the quartz repo with your changes, along with unit tests for the new dialect. The contributing guide should outline the process. Since you already have the SQL script, the next steps would be: integrate it into the codebase, ensure it follows existing patterns, add tests, and update documentation. Good luck with the contribution!
