• You might start a page on the INCAR-tag "tagname" as follows

{{TAGDEF|TAGNAME|val1 [{{!}} val2 {{!}} val3 {{!}} .. ] [|default] }}

Examples:

1. {{TAGDEF|NELM|[integer]}}

   NELM = [integer] 

2. {{TAGDEF|NELM|[integer]|60}}

   NELM = [integer]
   Default: NELM = 60 

3. {{TAGDEF|ISTART|0 {{!}} 1  {{!}} 2|0}}

   ISTART = 0 | 1 | 2
   Default: ISTART = 0 

• When an INCAR-tag has more than one default (a conditional default) use the following construct

{{TAGDEF|TAGNAME|val1 {{!}} val2 {{!}} val3}}
{{DEF|TAGNAME|default1|condition1|default2|condition2 [|default3|condition3] ... }}

TAGNAME = val1 | val2 | val3 

Default: TAGNAME	= default1	condition1
	= default2	condition2
	= default3	condition3

for instance

{{TAGDEF|ICHARG|0 {{!}} 1 {{!}} 2 {{!}} 4}}
{{DEF|ICHARG|2|if {{TAG|ISTART}}{{=}}0|0|else}}

ICHARG = 0 | 1 | 2 | 4 

Default: ICHARG	= 2	if ISTART=0
	= 0	else

The TAGDEF template can harbor up to six "default|condition" combinations.

• Followed by

Description: {{TAG|TAGNAME}} ...

and maybe lots of text ... like if you want to know how to put
in an equation in LaTeX style then have a look at the source of the {{TAG|PREC}} page

Description: TAGNAME ...

and your text maybe lots of text ... like if you want to know how to put in an equation in LaTeX style then have a look at the source of an equation array.

• By the way this is how to refer to all tags and files

{{TAG|TAGNAME}} and {{FILE|FILENAME}}

TAGNAME and FILENAME

• If you want to know how to quote whole pieces of input and output have a look at the source of ROPT and a page with pieces of INCAR text, or to the source of this page of course.

• To create a hook to which one may jump, for instance to the following equation array:

<span id="eqnarray">
<math>
\begin{align}
\frac{e}{\pi} & =\int_\Omega \psi (\mathbf{r}) d\mathbf{r} \\
a & = b \\
\end{align}
</math>
</span>

${\begin{aligned}{\frac {e}{\pi }}&=\int _{\Omega }\psi (\mathbf {r} )d\mathbf {r} \\a&=b\\\end{aligned}}$

You may then jump to the aformention equation array with

[[Vaspwiki_standards#eqnarray|an equation array]]

an equation array or to another example in another section.
