 ## User-defined: manual summary split:
 
-Alternatively, you may add the <code>&#60;&#33;&#45;&#45;more&#45;&#45;&#62;</code> summary divider[^1] where you want to split the article.  Content prior to the summary divider will be used as that content's summary, and stored into the `.Summary` variable with all HTML formatting intact.
+Alternatively, you may add the <code>&#60;&#33;&#45;&#45;more&#45;&#45;&#62;</code> summary divider[^1] (for org content, use <code># more</code>) where you want to split the article.  Content prior to the summary divider will be used as that content's summary, and stored into the `.Summary` variable with all HTML formatting intact.
 
 [^1]: The **summary divider** is also called "more tag", "excerpt separator", etc. in other literature.
 
 * Pros: Freedom, precision, and improved rendering.  All formatting is preserved.

 If there is nothing but spaces and newlines after the summary divider then `.Truncated` will be false.

-  Since 0.14, Hugo has defined a new concept called _external helpers_. It means that you can write your content using Asciidoc[tor], or reStructuredText. If you have files with associated extensions ([details](https://github.com/spf13/hugo/blob/77c60a3440806067109347d04eb5368b65ea0fe8/helpers/general.go#L65)), then Hugo will call external commands to generate the content.

If you have files with associated extensions ([details](https://github.com/spf13/hugo/blob/77c60a3440806067109347d04eb5368b65ea0fe8/helpers/general.go#L65)), then Hugo will call external commands to generate the content (the exception being Org-Mode content, which is parsed natively).
 
   This means that you will have to install the associated tool on your machine to be able to use those formats.
