+== Using Hashtags
+
+Hashtags are freeform strings associated with a change, like on social media
+platforms. In Gerrit, you explicitly associate hashtags with changes using a
+dedicated area of the UI; they are not parsed from commit messages or comments.
+
+Similar to topics, hashtags can be used to group related changes together, and
+to search using the link:user-search.html#hashtag[`hashtag:`] operator. Unlike
+topics, a change can have multiple hashtags, and they are only used for
+informational grouping; changes with the same hashtags are not necessarily
+submitted together.
