+===== Conclusion =====
+Great! So, we have successfully written a tiny operating system which can print text to the screen! This was a lot of work, and we learned a lot of new stuff about how computers work. We'll continue the next time when we will improve our assembly skills and learn some new stuff, by extending our operating system to print numbers to the screen. After that, we will get into the complex task of loading stuff from the disk.
+Thank you for watching and see you the next time! Bye bye!
