 It is possible to start a replay or save file directly from the terminal issuing the standalone {{{hwengine}}} utility with very simple syntax. 
 
 == Standard Use ==
-{{{$ hwengine [path to hedgewars folder] <path to data folder> <path to replay file>}}}
+{{{$ hwengine <path to replay file> [options]}}}
 
-The data folder is where you installed the game, or where you configured it at compile time.
-By default it is contained in the following directory:
-
-  * _Windows_: {{{%USERPROFILE%\Hedgewars}}}
-  * _Linux_: {{{~/.hedgewars}}}
-  * _Mac OS X_: {{{~/Library/Application Support/Hedgewars}}}
+By default hwengine will look in the current folder for game assets, if you wish to use another directory you should set the --prefix option.
 
 The replay file can be stored anywhere.
 
 == Advanced Use ==
 It is possible to specify settings by adding additional arguments:
 
-  * {{{--user-dir [path to hedgewars folder]}}} - Sets the path to game folder
+  * {{{--prefix [path to hedgewars folder]}}} - Sets the path to game folder
+  * {{{--user-prefix [path to hedgewars folder]}}} - Sets a secondary folder to find game content
   * {{{--locale [path to language file]}}} - Sets the game language
   * {{{--width [size]}}} - Starts the game with the given width (in pixels)
   * {{{--height [size]}}} - Starts the game with the given height (in pixels)
