 ## Configuration Options
 
+Configuration of spew is handled by fields in the ConfigState type. For
+convenience, all of the top-level functions use a global state available via the
+spew.Config global.
+
+It is also possible to create a SpewState instance which provides a unique
+ConfigState accessible via the Config method. The methods of SpewState are
+equivalent to the top-level functions. This allows concurrent configuration
+options. See the SpewState documentation for more details.

 ```
-* spew.Config.MaxDepth
+* MaxDepth
 	Maximum number of levels to descend into nested data structures.
 	There is no limit by default.
 
-* spew.Config.Indent
+* Indent
 	String to use for each indentation level for Dump functions.
 	It is a single space by default.  A popular alternative is "\t".
 
-* spew.Config.DisableMethods
+* DisableMethods
 	Disables invocation of error and Stringer interface methods.
 	Method invocation is enabled by default.
 
-* spew.Config.DisablePointerMethods
+* DisablePointerMethods
 	Disables invocation of error and Stringer interface methods on types
 	which only accept pointer receivers from non-pointer variables.
 	Pointer method invocation is enabled by default.
