Comments

How to leave notes for future-you without affecting the rendered output.

Squiggly recognizes a single comment form, started inside an action with //:

{{ // This won't appear in the output. }}

Everything from // to the closing }} is dropped at parse time. Useful for marking why a partial is being called or why a block is empty:

{{ partial 'sidebar' . }}
{{ // sidebar is intentionally rendered before the main column so its
   // search input gets keyboard focus first. }}
{{ block main . }} … {{ end }}

There is no /* … */ style. If you want a multi-line comment, use multiple single-line ones, or wrap in {{ if false }} … {{ end }} (the cost is the parser still walks the unused branch — fine for prose, expensive only if you nest very large templates).
