We are not currently in a position to accept direct financial contributions towards the development of MkLinux. The Linux community is nothing if not obsessively helpful. No one was born knowing how to use a Unix style operating system. Hang out in the mailing lists and offer people your assistance. Be polite and know when to say that you haven't got a clue.
Documentation plays a vital role in software development.
Users need documentation to help them learn the system, and software engineers need it to help them understand the system internals. While MkLinux is very closely aligned to the monolithic Linux system, it is not entirely the same. A wealth of documentation is available for Intel versions of Linux, but both MkLinux and LinuxPPC need additional documentation to elucidate the hardware differences. For example, PowerPC machines don't possess COM ports and IRQs. This site is the work of coders, not graphic designers and technical writers.
