 ## 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.

 ### 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).
