# Contributing

This is a DokuWiki installation. At the top of every **edit** page is a link to two important pages: the syntax page that describes the wiki syntax, and the playground page, which is a scratch page for playing around and experimenting.

You need an account to contribute. You must directly contact the maintainer of this wiki to get an account. Once you've been granted an account, you can view and edit *most* pages. Please be respectful of others. Please note that there are some pages that are restricted to those working on projects. If you are interested in joining those projects, email the maintainer.

## Plugins

There are many plugins enabled on this wiki. See plugins page form some of the things you can do.

## Create a Page for Yourself

If you have an account, please create a page for yourself in the `users`

namespace. The maintainer's page is:

sprowell |

`[[users:sprowell]]` |

## Adding Math

You can add mathematics to these pages using LaTeX. You can write the usual inline equations with `$..$`

delimiters, and display equations with `\[..\]`

. This is all done via MathJax. Follow that link for more information.

If you see something on a page, look at the page source to see how it was done. (That's part of the beauty of wikis.) It really isn't hard.

\[\begin{eqnarray} \int_0^\infty {1 \over x} \;dx & = & \lim_{y\to \infty} \lim_{z\to 0^+} \int_z^y {1 \over x} \;dx \\& = & \lim_{y\to \infty} \lim_{z\to 0^+} \left. \ln |x| \right]_z^y \\& = & \lim_{y\to \infty} \lim_{z\to 0^+} (\ln y - \ln z) \\& = & \lim_{y\to \infty} \ln y - \lim_{z\to 0^+} \ln z \\& = & \infty - 0 \\& = & \infty \end{eqnarray}\]

\[\begin{eqnarray} \int_0^\infty {1 \over x} \;dx & = & \lim_{y\to \infty} \lim_{z\to 0^+} \int_z^y {1 \over x} \;dx \\& = & \lim_{y\to \infty} \lim_{z\to 0^+} \left. \ln |x| \right]_z^y \\& = & \lim_{y\to \infty} \lim_{z\to 0^+} (\ln y - \ln z) \\& = & \lim_{y\to \infty} \ln y - \lim_{z\to 0^+} \ln z \\& = & \infty - 0 \\& = & \infty \end{eqnarray}\]

The reader should verify the above.
