+# ID3 Parser
+
+This is a pure ID3 parser based upon [getID3](https://github.com/JamesHeinrich/getID3). It supports the following ID3
+versions inside MP3 files:
+
+- ID3v1 (v1.0 & v1.1)
+- ID3v2 (v2.2, v2.3 & v2.4)
+
+## Usage
+
+```php
+<?php
+require_once __DIR__ . '/vendor/autoload.php';
+
+$analyzer = new \ID3Parser\ID3Parser();
+$tags = $analyzer->analyze('/tmp/myfile.mp3'));
+```
+
+## Why should I use this package over getID3 directly?
+
+getID3 has evolved to a state where it is having a lot of other features such as parsing a ton of other file formats and
+for some of it, it is even invoking external programs on the server. For example it is nowadays even supporting SVG files.
+
+Such a big parsing library can easily be haunted by security related bugs as for example [CVE-2014-2053](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-2053)
+and some other vulnerabilities have proven. This library takes the ID3 parsing code from getID3 and strips all other
+functions.
+
+In cases where reading the ID3v2 tags is sufficient this library is likely to be a more secure approach, if you need any
+of the advanced features of getID3 however you're likely to be unhappy with this library.
