+
+The purpose of the kin operator with examples:
+
+* Finds related tags, related tiddlers in any depth
+* Finds out where base tiddler originates and what other elements originate from it
+* Finds the ancestors and successors of a family member
+* Finds the "leaves" of the branch of the base tiddler in a tree-like structure (where the base tiddler is a leaf)
+* Finds the super- and subsets / groups of a mathematical set (where the base tiddler is a set)

Unlike table of contents, standard search and list of tags, this plugin offers these features in an organic, collaborative way.
