+
+## Installation
+
+This page contains information about installing the Library for PHP.
+
+### Requirements
+
+- PHP version 5.3.0 or greater
+- The GD PHP extension
+
+### Obtaining the client library
+
+There are two options for obtaining the files for the client library.
+
+#### Using Composer
+
+You can install the library by adding it as a dependency to your composer.json.
+
+```
+  "require": {
+    "davaxi/sparkline": "^1.1"
+  }
+```
+
+#### Cloning from GitHub
+
+The library is available on [GitHub](https://github.com/davaxi/Sparkline). You can clone it into a local repository with the git clone command.
+
+```
+git clone https://github.com/davaxi/Sparkline.git
+```
+
+### What to do with the files
+
+After obtaining the files, ensure they are available to your code. If you're using Composer, this is handled for you automatically. If not, you will need to add the `autoload.php` file inside the client library.
+
+```
+require '/path/to/sparkline/folder/autoload.php';
+```
+
+## Usage
+
+Exemple: 
+
+![Sparkline](https://raw.githubusercontent.com/davaxi/Sparkline/master/tests/data/testGenerate2-mockup.png)
+
+```
+<?php
+
+require '/path/to/sparkline/folder/autoload.php';
+
+$sparkline = new Davaxi\Sparkline();
+$sparkline->setData(array(2,4,5,6,10,7,8,5,7,7,11,8,6,9,11,9,13,14,12,16));
+$sparkline->display();
