Okay, so imagine you have a computer, and on that computer you want to run a cool program that does something really useful or fun. Normally, you'd have to install an entire operating system (like Windows or MacOS) first, and then install the program on top of that.
But what if I told you there was another way?
Enter IncludeOS! IncludeOS is a special kind of operating system that's really tiny and lightweight. It's like a super-duper basic version of an OS, that's designed specifically to run just one single program.
So instead of having to install a huge operating system, with all kinds of extra software and tools you don't need, you can just use IncludeOS to run your program directly on the computer's hardware.
This makes your program super fast and efficient, because it doesn't have to go through all the extra layers of an entire operating system. It's kind of like having a racecar, versus a big heavy truck. The racecar can go really fast because it's so streamlined and efficient, just like your program running on IncludeOS.
So in summary, IncludeOS is a super simple and fast way to run just one program, without needing a whole bunch of extra baggage.
