Sure, so `{{foo}}` is the field itself, and the `{{#foo}} {{/foo}}` around it is a conditional block. So if `foo` isn’t filled out, nothing between `{{#foo}} {{/foo}}` will render.

So if you did

```markdown
My name is {{foo}}

```

and foo wasn’t defined, you’d get “My name is” in a post

but if you use

```markdown
{{#foo}}My name is {{foo}}{{/foo}}

```

and foo is not defined, “My name is” will also be excluded from the post
