+Autosuggestions
+---------------
+
+Integrates zsh-autosuggestions into Prezto.
+
+Autosuggestions
+===============
+
+Integrates [zsh-autosuggestions][1] into Prezto, which implements the
+[Fish shell][2]'s autosuggestions feature, where the user can type in any part
+of a previously entered command and Zsh suggests commands as you type based on
+history and completions.
+
+If this module is used in conjuncture with the *syntax-highlighting* module, it
+must be loaded **after** it.
+
+If this module is used in conjuncture with the *history-substring-search*
+module, it must be loaded **after** it.
+
+Contributors
+------------
+
+New features and bug fixes should be submitted to the [zsh-autosuggestions][1]
+project according to its rules and regulations. This module will be synchronized
+against it.
+
+Settings
+--------
+
+### Highlighting
+
+If colors are enabled, *autosuggestions* will automatically highlight
+positive results.
+
+To enable highlighting for this module only, add the following line to
+*zpreztorc*:
+
+    zstyle ':prezto:module:autosuggestions' color 'yes'
+
+To set the query found color, add the following line to *zpreztorc*:
+
+    zstyle ':prezto:module:autosuggestions:color' found ''
+
+Authors
+-------
+
+*The authors of this module should be contacted via the [issue tracker][3].*
