You can do this using a GitHub Pull Request from a fork.
But before you start, please open an issue about your intention and wait for a project maintainer approve.
After that:
- Read more about the developing process.
- Fork the project.
- Make a new feature branch from the master branch on your forked project.
- Open a new Pull Request to the Seeneva/seeneva-reader-android master branch from your feature branch with pushed changes.
