-## Quick switching between Kernel and Userland targets
-
-In order to let CLion know what kind of code you're currently working on (Kernel / Userland) to make sure it parses and displays the correct half of statements like this:
-```c++
-#ifdef KERNEL
-...
-#else
-...
-#endif
-```
-You need to add build configurations for each:
-
-Click on one of the buttons below (top right of the IDE) - If you have the second one, press Edit Configurations after the dropdown box opens, then press CTRL+A to select the 1000s of automatically generated targets, and then press Delete to remove them.
-
-![Add Configuration...](CLion_Add_Configuration.png)
-![Kernel | Default](CLion_Add_Configuration_Existing.png)
-
-Then press the `+` button to add a new configuration, select `CMake Application`, name the configuration `Kernel`, set the target to `Kernel` (typing while the dropdown box is open searches), and then repeat the process one more time, this time with the name being `Userland` and the target being `true`.
-
-Finally, to quickly switch between the two different contexts, simply click the `Kernel | Default` / `Userland | Default` button to switch.
