 ## API
-### `blessPlugin([blessOptions[, pattern]])`
+### `blessPlugin([blessOptions[, pattern[, outputFilename]]])`
 
 - `blessOptions` is an options object for bless. It will be passed directly to it.
 - `pattern` a regular expression to find assets that should be transformed with bless. Default: `/\.css$/`.
-
-
-
+- `outputFilename` a filename for the blessed css files. If set, the original (unblessed) files will also be emitted. The following variables can be used:
+  - `[filebase]` The base name of the asset, without path or extension
+  - `[file]` The full name of the asset, including path and extension
