This template usually takes two parameters, like this:
If the template is on a "Template:" page, it will return this:
If the template is on any other page, it will return this:
A typical usage case could be to make it so that a template only adds a category when not on a template page. Thus not adding the template itself and other templates that are built with it to the category. Like this:
Note that in the example above the "template" parameter was left empty.
For testing and demonstration purposes this template can take a parameter named demospace. 
Like this:
{{template other 
| Template page text 
| Other pages text 
| demospace = template
No matter on what kind of page the code above is used it will return this:
| Template page text 
| Other pages text 
| demospace = template
You can make it so your template also understands the demospace parameter. That means you can demonstrate the different appearances of your template in the documentation for your template. Then do like this:
{{template other 
| Template page text 
| Other pages text 
}
This template detects "Template talk:" pages as type other.
