+Fasd
+====
+
+[Fasd][1] is a command-line productivity booster, inspired by tools like
+[autojump][2], [z][3] and [v][4], it offers quick access to files and
+directories by keeping track of files and directories  that were previously
+accessed.
+
+For completion to work, this module must be loaded **after** the *completion*
+module.
+
+The Prezto Fasd configuration differs from the default. The default aliases have
+been disabled.
+
+Aliases
+-------
+
+  - `j` changes the current working directory interactively.
+
+Completion
+----------
+
+Type `,`, `f,`, `d,` in front of a comma-separated query or type `,,`,  `,,f`,
+`,,d` at the end of a comma-separated query then hit <kbd>tab</kbd>.
+
+Authors
+-------
+
+*The authors of this module should be contacted via the [issue tracker][5].*
