+This is a sort of OS built in Python, not bootable, but creates a custom directory structure and path definition.
+This is the "kernel", it hosts all features and runs all programs.
+For safety reasons the kernel is isolated, which means that with every shell instance,
+A new kernel instance will follow it. Same goes for every program, it will need to call upon a brand-new kernel instance.
