+
+@enumerate
+@item golden master/approval/snapshot testing.  The idea is that you have a
+  function with a currently unknown result and you want to write a tests, which
+  ensures that the result does not change during refactoring.
+@item Compare things which are complex like lists with lot of numbers or
+  complex data structures.
+@item Things which might change during the development like error messages.
+@end enumerate
+
+@code{inline-snapshot} automates the process of recording, storing and
+updating the value you want to compare with.  The value is converted with
+@code{repr()} and stored in the source file as argument of the
+@code{snapshot()} function.")
