 ### Creating Mongoose Schemas
 
-Place your Mongoose schema files in the a directory and specify that path in SCHEMA_PATH var
-Make sure mongoose npm package is installed globally or within that path
+Place your Mongoose schema object files in the a directory and specify that path in SCHEMA_PATH var
+Make sure file names reflect the collection name
