 ## Introduction
 
-Web-based client-side Quansheng UV-K5 firmware patcher written in Javascript and HTML using [Bootstrap 4.6.0](https://getbootstrap.com/docs/4.6/getting-started/introduction/), jQuery and parts of the [SB Admin 2 Theme](https://startbootstrap.com/theme/sb-admin-2).  
+Web-based client-side Quansheng firmware patcher written in Javascript and HTML using [Bootstrap 4.6.0](https://getbootstrap.com/docs/4.6/getting-started/introduction/), jQuery and parts of the [SB Admin 2 Theme](https://startbootstrap.com/theme/sb-admin-2).  
 It is based on the discoveries by the many contributors in the [uvmod-kitchen](https://github.com/amnemonic/Quansheng_UV-K5_Firmware/tree/main/uvmod_kitchen) and implements the same functionality in a modular and flexible javascript structure. 
 
 Visitors can generate a patched firmware image by selecting the desired patches. Patches modify the firmware on a binary level and can accept user input to customize variables. A custom base image can be supplied to allow support for mods that are compiled and linked directly into the firmware.
