\title{Hello, world!}
Here is a hello-world template document to illustrates a few \ConTeXt\
features. Have fun. You can find a lot more information at
\from[wiki]; the preceding text should be colored and clickable, and
clicking it should take you to the wiki.
\subject{A list}
Here is an example of a list.
\startitemize[a] % tags are lowercase letters
\item first
\item second
\item third
\stopitemize
\subject{Math}
An equation can be typeset inline like $e^{\pi i}+1=0$, or as a
displayed formula:
\startformula
\int_0^\infty t^4 e^{-t}\,dt = 24.
\stopformula
% don't use $$...$$ (the plain TeX equivalent)
You can also have numbered equations:
\placeformula[eq:factorial-example]\startformula
\int_0^\infty t^5 e^{-t}\,dt = 120.
\stopformula
And you can refer to them by name. I called the previous equation {\tt
factorial-example}, and it is equation \in[eq:factorial-example].
\ConTeXt\ figures out the number for you. And with interaction turned
on, you can click on the equation number to get to the equation.
\subject{Text with figures}
Now text with a few figures. The first figure goes on the right, with
the paragraph flowing around it.
\placefigure[right,none]{}{\externalfigure[dummy]}
\input tufte
The next figure will go inline, like a displayed formula:
