+      NestedText is a file format for holding data that is to be entered,
+      edited, or viewed by people. It allows data to be organized into a nested
+      collection of dictionaries, lists, and strings. In this way it is similar
+      to JSON, YAML and TOML, but without the complexity and risk of YAML and
+      without the syntactic clutter of JSON and TOML. NestedText is both simple
+      and natural. Only a small number of concepts and rules must be kept in
+      mind when creating it. It is easily created, modified, or viewed with a
+      text editor and easily understood and used by both programmers and
+      non-programmers.
