Child topic D

Another way to nest topics is to use a subfolder that contains its own toc.yml file that defines the TOC for that folder. To do this, link to the toc.yml file from the main manual TOC:

* [Documentation Tool](index)
* [External Links](ExternalLinks.md)
* [Parent Topic](subfolder/ParentTopicA.md)
    * [Child Topic B](subfolder/subfolder/ChildTopicB.md)
    * [Child Topic C](ChildTopicC.md)
    * [Nested TOC](subfolder/subfolderWithTOC/toc.yml)

In this case, the parent node in the main TOC does not have its own topic. (You can specify such a topic link when referencing from another YAML-format TOC file, but not from a markdown-format TOC file.)
