Requires QEMU installed and a manually created disk image before the kernel will boot, readme does not document what the OS supports once running.

In plain English

Misericordioso-os is a project written in C that describes itself, through its file names and build commands, as a small operating system kernel, though its readme provides almost no explanation of what the operating system actually does or what capabilities it has. The entire visible documentation consists only of setup and run instructions rather than a description of features. To build the project, the instructions say to simply run make from the project's terminal. Running the result requires QEMU, a virtual machine emulator, launched with the built kernel binary and an IDE formatted disk image, showing its display inside the terminal itself using QEMU's curses text mode rather than a graphical window. If no disk image exists yet, the readme shows how to create a blank four megabyte one using the standard dd command before first booting the system. A separate tip suggests the whole build and run process can also be done inside Termux, a terminal app for Android phones, meaning this small operating system can apparently be compiled and tested on a phone as well as on a regular computer. Beyond these bare setup steps, the readme does not explain what the operating system supports once it boots, what hardware or features it implements, or what problem it was built to solve. There is no license file referenced anywhere in the readme, and the repository itself has no description field filled in. Someone interested in this project would need to read the actual C source code directly to understand what Misericordioso-os actually does, since the available documentation only covers how to compile and launch it, not what happens afterward.
