For modding the Wii, <a href="https://sourceforge.net/projects/modmii/">we recommend using ModMii (if you have Windows)</a>. It works better, and you can get a guide generated with instructions.
However, it does not give instructions on how to install RiiConnect24 or Wiimmfi, so use the pages here to learn how to install it.
