 Many others have contributed as well, in [code contributions](https://github.com/jupyterlab/jupyterlab-git/graphs/contributors), funding, design, and guidance. Of course this project also exists only because of the monumental efforts at all levels of open source, in particular to the JupyterLab and Jupyter ecosystems, which this directly builds on.
