+### Escaping Shortcodes (For Documentation)
+
+When writing documentation *about* shortcodes (or anytime you need to display `{{< >}}` or `{{% %}}` without Hugo executing them), you **MUST** use Hugo's built-in comment syntax inside the delimiters.
+
+**The Rule:** Place `/*` immediately after the opening delimiter, and `*/` immediately before the closing delimiter. **No spaces are allowed between the delimiter and the comment marker.**
+
+*   **Correct (Angle Brackets):** `{{</* shortcode_name */>}}`
+*   **Correct (Percentage Signs):** `{{%/* shortcode_name */%}}`
+*   **Correct (Inner only):** `{{/* shortcode_name */}}` (If you just want to show the generic brackets without `< >` or `% %`)
+
+**Common Mistakes that break the build:**
+*   ❌ `{{< /* shortcode */ >}}` (Spaces around the comment markers cause parsing errors or unrecognized characters)
+*   ❌ `{{/*< shortcode >*/}}` (Comment markers placed outside the inner delimiters)
+*   ❌ `&#123;&#123;` (Using HTML entities is unnecessary, harder to read in source, and can break copy-pasting)
