 Carbon CSV
 ==========
 
-Carbon CSV is a PHP library, that helps you easily parse CSV files.
-Parse any CSV file to an easy to use associative array.
+Carbon CSV is a PHP library aimed at simplifying CSV parsing.
 
-## Features
-
-There are a number of helpful features that include:
-
-* reduced memory usage and size, thanks to the [`SplFileObject`](http://php.net/manual/en/class.splfileobject.php) PHP class;
-* skip row until (by index);
-* skip specific columns (by index);
-* column removal from parsed output (by index - single or multiple columns). If you wish to remove columns you don't need to work with;
-* set custom column names, which will help you when using the parsed output.
+It provides simple interface to ease mapping columns via a header row, or custom column names. 
 
 ## Installation
 
-It is recommended to install the library through [Composer](https://getcomposer.org/).
-
 ```bash
 composer require htmlburger/carbon-csv
 ```
 
 ## Usage
 
-To parse a simple CSV file, use the following code:
+Suppose that you have the following CSV:
 
-```php
-use \Carbon_CSV\CsvFile as CsvFile;
-use \Carbon_CSV\Exception;
+| First Name | Last Name | Company Name                    | Address                             |
+|------------|-----------|---------------------------------|-------------------------------------|
+| Homer      | Simpson   | Springfield Nuclear Power Plant |  742 Evergreen Terrace, Springfield |
+| Ned        | Flanders  | The Leftorium                   | 744 Evergreen Terrace, Springfield  |
 
-$csv = new CsvFile('path-to-file/filename.csv');
-foreach ($csv as $row) {
-    /* do something with $row*/
+Here is how you could iterate through the rows:
+
+```php
+use \Carbon_CSV\CsvFile;
+use \Carbon_CSV\Exception as CsvException;
+
+try {
+    $csv = new CsvFile('path-to-file/filename.csv');
+    $csv->use_first_row_as_header();
+
+    foreach ($csv as $row) {
+        print_r($row);
+    }
+} catch (CsvException $e) {
+    exit("Couldn't parse CSV file: " . $e->getMessage()); 
 }
 ```
 
-You can iterate the `$csv` object directly, or get all the rows using the `to_array` method.
+Would produce the following output: 
 
-**Important:** the above approach is preferred, as it's less taxing - memory wise (it only works with one row at a time, and doesn't hold all of them, like `to_array` does).
+```
+Array
+(
+    [First Name] => Homer
+    [Last Name] => Simpson
+    [Company Name] => Springfield Nuclear Power Plant
+    [Address] => 742 Evergreen Terrace, Springfield
+)
+Array
+(
+    [First Name] => Ned
+    [Last Name] => Flanders
+    [Company Name] => The Leftorium
+    [Address] => 744 Evergreen Terrace, Springfield
+)
+```
 
-Here's an example with the `to_array` method.
+Alternatively, you could also provide your own column names:
 
 ```php
-use \Carbon_CSV\CsvFile as CsvFile;
-use \Carbon_CSV\Exception;
-
-$csv = new CsvFile('path-to-file/filename.csv');
-$rows = $csv->to_array();
+use \Carbon_CSV\CsvFile;
+use \Carbon_CSV\Exception as CsvException;
+
+try {
+    $csv = new CsvFile('path-to-file/filename.csv');
+    $csv->use_first_row_as_header();
+    $csv->set_column_names([
+        'First Name'   => 'fname',
+        'Last Name'    => 'lname',
+        'Company Name' => 'company',
+        'Address'      => 'address',
+    ]);
+
+    foreach ($csv as $row) {
+        print_r($row);
+    }
+} catch (CsvException $e) {
+    exit("Couldn't parse CSV file: " . $e->getMessage()); 
+}
 ```
 
-This will parse the file and assign the result to the `$rows` variable.

-Output:
+Would produce the following output: 
 
 ```
