Handlebars syntax

Here's a short guide to Handlebars syntax. For more information, consult the official Handlebars documentation.
Variables
You refer to variables like this:
{{ variable_name }}
If the variable is an object with properties of its own, you can refer to them like so:
{{ person.firstName }}
This is how you refer to a specific index of an array:
{{ people.[0] }}
Comments
You can use Handlebars comments in your files. Commented out sections won't show up in the final rendered output.
{{! This comment will not show up in the output}}
If the content you want to comment out contains }} or other Handlebars tokens, you need to use different comment style: 
{{!-- This comment may contain mustaches like }} --}}
If-conditions
Here's an example of if-condition:
{{#if some_variable}}
  this will be included in the output
{{/if}}
Iterating over collections
This is how you iterate over a collection of items:
{{#each securityGroupIds}}
  - {{this}}
{{/each}}
