 ## About The Project
 With this app you can conveniently add, manage or simply find documents stored in your paperless server without any comproimises. This project started as a small fun side project to learn more about the Flutter framework and because existing solutions didn't fulfill my needs, but it has grown much faster with far more features than I originally anticipated.
