 ### Include the library
 
 #### Composer
-If you are using composer, then add `mike42/escpos-php` as a dependency:
 
-```bash
-composer require mike42/escpos-php
-```
-
-In this case, you would include composer's auto-loader at the top of your source files:
-
-```php
-<?php
-require __DIR__ . '/vendor/autoload.php';
-```
-
-#### Manually
-If you don't have composer available, then simply download the code and include `autoload.php`:
+This library is designed for use with the `composer` PHP dependency manager. Simply add the `mike42/escpos-php` package to get started:
 
 ```bash
-git clone https://github.com/mike42/escpos-php vendor/mike42/escpos-php
+composer require mike42/escpos-php
 ```
 
-```php
-<?php
-require __DIR__ . '/vendor/mike42/escpos-php/autoload.php';

+- `zlib` extension, used for de-compressing bundled resources (see [documentation](https://www.php.net/manual/en/book.zlib.php)).

 For a list of available profiles, or to have support for your printer improved, please see the upstream [receipt-print-hq/escpos-printer-db](https://github.com/receipt-print-hq/escpos-printer-db) project.
 
 ### Tips & examples
+
 On Linux, your printer device file will be somewhere like `/dev/lp0` (parallel), `/dev/usb/lp1` (USB), `/dev/ttyUSB0` (USB-Serial), `/dev/ttyS0` (serial).
 
 On Windows, the device files will be along the lines of `LPT1` (parallel) or `COM1` (serial). Use the `WindowsPrintConnector` to tap into system printing on Windows (eg. [Windows USB](https://github.com/mike42/escpos-php/tree/master/example/interface/windows-usb.php), [SMB](https://github.com/mike42/escpos-php/tree/master/example/interface/smb.php) or [Windows LPT](https://github.com/mike42/escpos-php/tree/master/example/interface/windows-lpt.php)) - this submits print jobs via a queue rather than communicating directly with the printer.
