# Template:Rule of thumb

The following template description is not displayed when the template is inserted in an article.

## Goal

This template is used to highlight rules of thumb within a page.

## Usage

This template can be used in a short and a long form. If the is only one rule of thumb the short form can be used, if there are more rules of thumb you would have to use the long form.

### Short form parameters

```{{rule of thumb |rule |motivation}}
```

In this form both parameters are mandatory.

rule
Rule of thumb
motivation
Something to help remember it

### Long form parameters

```{{rule of thumb
| topic       =
| rule        =
| motivation  =
| rule2       =
| motivation2 =
| rule3       =
| motivation3 =
}}
```
topic
Optional common topic.
rule(n)
Rule of thumb. The first is mandatory.
motivation(n)
Something to help remember it. The first is mandatory.

On order to make the rules of thumb easier to remember:

• It is advised to not use more than three rules of thumb.
• Have them spread out in the article rather than having them collected in the bottom of it.
• Supply a short motivation or something else to help explain them.

## Examples

```
