About project
This project showcases my contributions to various open source initiatives, highlighting the importance of collaboration and community in software development.
Over the years, I have been contributing to open source projects. However, maximum changes can be categorized into either 1) Document changes 2) Adding Odia language support to projects. Here are a detailed list of PRs (Pull Requests) I have contributed.

PRs are not the only way to contribute. I also engage with the community through discussions, issue reporting, and providing feedback on other contributions. Those I do not know how to quantify.
I will try to keep track of these contributions in the future to better showcase my involvement in the open source community. Open source is the best way to learn, collaborate, and make a positive impact on the software ecosystem.
