Hi Aditya,
First of all, thank you that you are considering contributing to the release-bot project.
If you would like to know more about the project, all information is in the upstream repository [1]. If you would like to fix some issues, please read our contributing guidelines [2] first.
Feel free to contact us with any questions or even create a GitHub issue if there is anything unclear - specifically, these kinds of questions are very important because the documentation should be clear to everyone, especially newcomers.
