 ## User Interfaces
 
-Jacksum provides a command line interface (CLI), and an application programming interface (API). A graphical user interface (GUI) is provided by HashGarten which is a subproject of the Jacksum project. Also, there are file browser integrations (FBI) available to integrate Jacksum and HashGarten into your preferred file browser such as Finder on macOS, Windows Explorer on Microsoft Windows or Caja, Dolphin, elementary Files, Konqueror, Krusader, Nemo, GNOME Nautilus, ROX-Filter, SpaceFM, Thunar, Xfe, or zzzFM on GNU/Linux.

 ### CLI

 ### GUI
 
 If you prefer a graphical user interface (GUI) and you just would like to calc and verify hashes with a graphical user interface, I recommend to download and use the Jacksum File Browser Integration (FBI) installer which comes with [HashGarten](https://github.com/jonelo/HashGarten) that is a GUI for Jacksum. The installer is available for many different file managers on Windows, Linux, and macOS. See also [Integrations](https://github.com/jonelo/jacksum#integrations).
