installed my own WiKi

so, due to a brain-fart idea i had in another thread, i installed a WiKi on my site. i quickly found that i have no idea how to even work with a Wiki. :D i have read from a Wiki several times, but i have never edited one, to my knowledge.

my intention was to create an Arduino/C++/Electronics information area, and allow (somehow) for it to be mirrored with somebody elses Wiki, with the intent of providing a durable set of basic information. I used Media Wiki. sadly, i have no idea how to even administrate it. :D :D :D
