+A Python package for facilitating and unifying access to global streamflow data.
 
 Welcome to RivRetrieve-Python! We're actively developing this library to make global streamflow data more accessible. As an early-stage project, it's not yet stable, and we appreciate your understanding as things evolve. Contributions and feedback are welcome! Please check out the active development under [Issues](https://github.com/kratzert/RivRetrieve-Python/issues) or start posting under [Discussions](https://github.com/kratzert/RivRetrieve-Python/discussions).
