-This plugin renders LaTeX formulas into images.
+This plugin provides a [[ikiwiki/directive/teximg]] [[ikiwiki/directive]],
+that renders LaTeX formulas into images.
 
-Of course you will need LaTeX installed for this to work. The plugin
-also uses mhchem.sty, which in Debian is in the texlive-science package and
-may not be part of a regular texlive installation.
+You will need LaTeX installed for this to work, specifically something
+providing `latex` in the path. You will also need either `dvipng` or a
+combination of `dvips` and `convert` from ImageMagick/GraphicsMagick.
 
-## examples
-
-       \[[!teximg code="\ce{[Cu(NH3)3]^{2+}}"]]
-       \[[!teximg code="\frac{1}{2}"]]
-       \[[!teximg code="E = - \frac{Z^2 \cdot  \mu \cdot e^4}{32\pi^2 \epsilon_0^2 \hbar^2 n^2}" ]]
-
-To scale the image, use height=x:
-
-       \[[!teximg code="\ce{[Cu(NH3)3]^{2+}}" height="17"]]
-       \[[!teximg code="\ce{[Cu(NH3)3]^{2+}}" height="8"]]
-
-If no height is choosen the default height 12 is used. Valid heights are: 8, 9,
-10, 11, 12, 14, 17, 20. If another height is entered, the closest available
-height is used.
-
-To add an alt text to the image, use alt="text":
-
-       \[[!teximg code="\frac{1}{2}" alt="1/2"]]
-
-See [this site](http://www.der-winnie.de/opensource/gsoc2007) for rendered images.
+On Debian systems, the relevant package names are `texlive-latex-base`
+and either `dvipng` or `graphicsmagick-imagemagick-compat`.
