 # mime
 
-Support for mapping between file extensions and MIME types.  This module uses the latest version of the Apache "mime.types" file (maps over 620 types to 800+ extensions).  It is also trivially easy to add your own types and extensions, should you need to do that.
+Comprehensive MIME type mapping API. Includes all 600+ types and 800+ extensions defined by the Apache project, plus additional types submitted by the node.js community.
