 [[TiddlyWikiFolders]] are configured with a single `tiddlywiki.info` file in the root of the wiki folder. It should contain a JSON object comprising the following properties:

-* ''themes'' - an array of theme names to be included in the wiki
-* ''languages'' - an array of language names to be included in the wiki
-* ''includeWikis'' - an array of references to external wiki folders to be included in the wiki

+The ''build'' property contains a hashmap of named build targets. Each of the build targets is defined as an array of command tokens.
+
 Note that the build targets of included wikis are merged if a target of that name isn't defined in the current `tiddlywiki.info` file.
 
+Command tokens can be a simple string or a command token object with a ''type'' property. The following types are defined to allow the command token to be dynamically defined:
+
+* ''filter'': the value of the first result of a filter expression specified in the ''text'' property of the command token object
+* ''wikify'': the result of wikifying a text string specified in the ''text'' property of the command token object
+* ''prompt'': the result of prompting the user for a string. The ''prompt'' property of the command token object specifies the textual prompt to be used. The optional ''default'' property specifies a string value to be used if the user presses enter in response to the prompt
+
+The EchoCommand is useful for debugging complex dynamic command tokens.
