-This plugin renders LaTeX formulas into images, which are rendered automatically when you save this site. 
-
-Scaling of this images is of course also possible, possible heights are:
-
-  8,9,10,11,12,14,17,20
-
-But is also work if you pic e.g. another height. The best fitting height is then used to generate the image.
-
-#Here are some examples how to use this plugin:
-
-        [[tex code="\ce{[Cu(NH3)3]^{2+}}"]]
-        [[tex code="\frac{1}{2}"]]
-        [[tex code="E = - \frac{Z^2 \cdot  \mu \cdot e^4}{32\pi^2 \epsilon_0^2 \hbar^2 n^2}" ]]
-
-in order to scale this images use height=x:
-
-        [[tex code="\ce{[Cu(NH3)3]^{2+}}" height="17"]]
-        [[tex code="\ce{[Cu(NH3)3]^{2+}}" height="8"]]
-
-If no height is choosen the default height 12 is used.
