Here is a skeleton document that illustrates several features of ConTeXt:

File:Hello-world.pdf is the PDF file the 2006.12.27 version of ConTeXt produced.


File:Hello-world.tex is the source (to save copying and pasting from the source below).

Words starting with a backslash (such as \starttext) are called command sequence or macros. To mark the content to be typeset, one uses the macros


To mark a headline and the content of a section, one uses the macros:

\title{Hello, world!}

Here is a hello-world template document to illustrate 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


An equation can be typeset inline like $e^{\pi i}+1=0$, or as a
displayed formula:
\int_0^\infty t^4 e^{-t}\,dt = 24.
% don't use $$...$$ (the plain TeX equivalent)
You can also have numbered equations:
\int_0^\infty t^5 e^{-t}\,dt = 120.
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.


\input tufte

The next figure will go inline, like a displayed formula:
\input tufte

Here's another reference to the numbered equation -- equation
\in[eq:factorial-example] on \at{page}[eq:factorial-example], so that
you can test clicking on it or on the page reference.

% most plain TeX commands work
