+If you're using Karabiner Elements on your Mac, then stop here! Make sure to close Karabiner Elements, then try to reproduce the issue again, even if you think that Karabiner Elements shouldn't be the cause. Karabiner Elements is the source of numerous problems, and we don't want to receive any more reports it causes.

 3. In the IDE, import the project by invoking *File -> Import -> General -> Existing Projects into Workspace*, select the *left* or *right* directory depending on the desired firmware, then click on the *Finish* button.
 
-## Building and flashing the firmware
+4. In order to be able to flash the firmware via USB from the IDE, you must build [Agent](https://github.com/UltimateHackingKeyboard/agent) which is Git submodule of the this repo and located in the `lib/agent` directory.
 
-For the left keyboard half, make sure to power it via the right keyboard half (which must be powered via USB). Also connect the left keyboard half to your SEGGER J-Link USB debug probe (which must also be connected via USB). Then in KDS, click on *Run -> Run Configurations*, select *GDB SEGGER J-Link Debugging -> uhk60-left_release_jlink*, and click on the *Debug* button.
+5. Finally, in the IDE, click on *Run -> External Tools -> External Tools Configurations*, then select a release firmware to be flashed such as *uhk60-right_release_kboot*, and click on the *Run* button.
 
-For the right keyboard half, flash [the bootloader](https://github.com/UltimateHackingKeyboard/bootloader) first.
-
-At this point, you can flash the right firmware via USB from KDS. To achieve this, you must build [Agent](https://github.com/UltimateHackingKeyboard/agent) that is Git submodule of the this repo and located in the `lib/agent` directory.  Then in KDS, click on *Run -> Run Configurations*, select *C/C++ Application -> uhk60-right_release_kboot*, and click on the *Run* button.
-
-From this point on, you can upgrade the firmwares of both halves via USB by using the uhk60-left_release_kboot and uhk60-right_release_kboot run configurations. Alternatively, you can use your SEGGER J-Link probe.
+Going forward, it's easier to flash the firmware of your choice by using the downwards toolbar icon which is located rightwards of the *green play + toolbox icon*.
