+    (description
+      "This is a package to perform text folding like in Vim.  It has the
+following features:
+
+* folding of active regions;
+* good visual feedback: it's obvious which part of text is folded;
+* persistence by default: when you kill a buffer your folds don't
+  disappear;
+* persistence scales well, you can work on hundreds of files with lots of
+  folds without adverse effects;
+* it does not break indentation;
+* folds can be toggled from folded state to unfolded and back very
+  easily;
+* quick navigation between existing folds;
+* you can use mouse to unfold folds (good for beginners and not only for
+  them);
+* for fans of `avy package: you can use `avy' to fold text with minimal
+  number of key strokes!")
