You can find detailed guides for Linux kernel developers and users in the Documentation/ folder, which includes files in formats like HTML and PDF. To build these documents yourself, use commands like `make htmldocs` or `make pdfdocs`. The documentation covers important topics such as kernel building, running requirements, and upgrade issues. You can also view the latest formatted docs online. Additionally, the kernel source uses a special comment style called kernel-doc to embed documentation directly in the code, making it easier to understand functions and structures. This helps you learn, build, and maintain the Linux kernel more effectively.

You can build C projects using only a C compiler without needing tools like make or cmake by using the "nob" library, which lets you write build instructions in C itself. This makes your build process very portable across many systems (Linux, Windows, MacOS, etc.) because it depends only on the C compiler, which is widely available. It also lets you reuse code between your project and build system since both use C. However, it requires comfort with C programming and is mainly useful for simpler C/C++ projects, not complex ones with many dependencies. You just include the single header file "nob.h" to start using it. This approach simplifies building and increases control if you prefer coding your build steps in C directly.
