+# Comments
+
+!> Comments requires an understanding of [Sections](usage/sections.md) and [Paragraphs](usage/paragraph.md).
+
+## Intro
+
+To add comments in `docx`, a `comments` block is specified in the `Document`. This block defines all the comments in your document. Each comment has an `id`, which you then reference later.
+
+In the spot you want to add a comment, you simply add a `CommentRangeStart` and a `CommentRangeEnd` to specify where the comment starts and ends.
+
+Alternatively, you can use `CommentReference` to specify a comment at a specific singular point.
