 Multer
 ======
 
-Multer is a Connect middleware for handling multipart/form-data
+Multer is a Connect middleware for handling **multipart/form-data**. It can be used with both Connect and Express, seamlessly. It is based on [busboy](https://github.com/mscdex/busboy). 
 
+## Usage
+
+Install the Multer package from npm:
+
+    $ npm install multer
+
+Include the Multer middleware in your app:
+
+    ...
+    var multer = require('multer');
+    app.use(multer({ dest: './uploads/'}));
+    ...
+
+**IMPORTANT**: Multer will not process any form which not **multipart/form-data** submitted via the **POST** method.
+
+## Multer file object
+
+A multer file object is a JSON object with the following properties.
+
+1. `fieldname` - Field name specified in the form
+2. `originalname` - Name of the file on the user's computer
+3. `name` - Renamed file name
+4. `encoding` - Encoding type of the file
+5. `mimetype` - Mime type of the file
+6. `path` - Location of the uploaded file
+7. `extension` - Extension of the file
+
+## Options
+
+Multer accepts an options object, the most basic of which is the `dest` property, which tells Multer where to upload the files to. In case you omit the options object, the file will be renamed and uploaded to the temporary directory of the system.
+
+By the default, Multer will rename the files so as to avoid name conflicts. The renaming function can be customized according to your needs.
+
+The following are the options that can be passed to Multer.
+
+1. `dest`
+2. `rename(fieldname, filename)`
+3. `onFileUploadStart(file)`
+4. `onFileUploadData(file, data)`
+5. `onFileUploadComplete(file)`
+6. `onParseStart()`
+7. `onParseEnd()`
+8. `onError()`
+
+In an average web app, only `dest` and `rename` might be required, and configured as shown in the example.
+
+    app.use(multer({
+      dest: './uploads/',
+      rename: function(fieldname, filename) {
+        return filename.replace(/\W+/g, '-').toLowerCase() + Date.now();
+      }
+    }));
+
+The details of the properties of the options object is explained in the following sections.
+
+###dest
+
+The destination directory for the uploaded files.
+
+Example:
+
+    dest: './uploads/'
+
+###rename(fieldname, filename)
+
+Function to rename the uploaded files. Whatever the function returns will become the new name of the uploaded file (extension is not included). The `fieldname` and `filename` of the file will be available in this function, use them if you need to.
+
+Example:
+
+    rename: function(fieldname, filename) {
+      return fieldname + filename + Date.now();
+    }
+
+###onFileUploadStart(file)
+
+Event handler triggered when a file starts to be uploaded. A file object with the following properties are available to this function: `fieldname`, `originalname`, `name`, `encoding`, `mimetype`, `path`, `extension`.
+
+Example:
+
+    onFileUploadStart: function(file) {
+      console.log(file.fieldname + ' is starting ...');
+    }
+
+###onFileUploadData(file, data)
+
+Event handler triggered when a chunk of buffer is received. A buffer object along with a file object is available to the function.
+
+Example:
+
+    onFileUploadData: function(file, data) {
+      console.log(data.lenth + ' of ' + file.fieldname + ' arrived');
+    }
+
+###onFileUploadComplete(file)
+
+Event handler trigger when a file is completely uploaded. A file object is available to the function.
+
+Example:
+
+    onFileUploadComplete: function(file) {
+      console.log(file.fieldname + ' uploaded to  ' + file.path);
+    }
+
+###onParseStart()
+
+Event handler triggered when the form parsing starts.
+
+Example:
+
+    onParseStart: function() {
+      console.log('Form parsing started at: ', new Date());
+    }
+
+###onParseEnd()
+
+Event handler triggered when the form parsing completes.
+
+Example:
+
+    onParseStart: function() {
+      console.log('Form parsing completed at: ', new Date());
+    }
+
+###onError()
+
+Event handler for any errors encountering while processing the form. The `error` object and the `next` object is available to the function. If you are handling errors yourself, make sure to terminate the request or call the `next()` function, else the request will be left hanging.
+
+Example:
+
+    onError: function(error, next) {
+      console.log(error);
+      next(error);
+    }
