I’m storing an address as an array in my config file. I’m interating over the array to render put each index on it’s own line by appending the HTML with an   
 tag. The problem is, that the   
 after the last index is unnecessary.

To prevent this I only want to add an   
 of the item is not the last one of the array.

My current template looks like this:

```auto
<p>
    {{ range .Site.Params.address }}
        {{ . }}<br>
    {{ end }}
</p>

```
