Kinda meh because it obviously won't work when viewed via another Markdown parser, but it's not too terrible, either. Better than introducing <!--[OC:...]--> or something like that...

# Headline with more lines [with link](huehue) and *some* more
This is some test text for the subset of Markdown supported by the planned ingame documentation system for OpenComputers.
![opencomputers:transistor](../../textures/gui/button_power.png)
*This* is *italic* text, ~~strikethrough~~ maybe abc-ter **some** text **in bold**. Is _this underlined_? Oh, no, _it's also italic!_ Well, this \*isn't bold*.
![This is a tooltip...](../../textures/gui/printer_ink.png)
*This* is *italic* text, ~~strikethrough~~ maybe abc-ter **some** text **in bold**. Is _this underlined_? Oh, no, _it's also italic!_ Well, this [a link](blah).
![This is rendered live.](oredict:oc:assembler)
## Smaller headline [also with *link* but this __one__ longer](huehue)
![This is another tooltip.](item:OpenComputers:item@23)
![All the colors.](oredict:craftingPiston)
This is *italic
over two* lines. But *this ... no *this is* **_bold italic_** *text*.
