 Lightweight configuration writer for PHP.
+
+## Installation
+
+### Requirements
+
+MonologPHPMailer requires *[PHP][link-php] 5.5.9* or higher.
+Also, the config directory needs to be writable by web server in order to save config file.
+
+### Using Composer
+
+The reccomended way to install ConfigWriter is with [Composer][link-composer], dependency manager for PHP.
+
+You should just require `filips123/config-writer` in your project.
+
+```bash
+composer require filips123/config-writer:^2.0
+```
+
+You would only need to include autoloader and namespace in your script.
+
+```php
+<?php
+
+use ConfigWriter\Config;
+
+require 'vendor/autoload.php';
+
+$config = new Config;
+```
+
+### Manually Installation
+
+Alternatively, you could download files from GitHub and then manually include them in your script.
+
+You whould need to include all files and namespace in your script.
+
+```php
+<?php
+
+use ConfigWriter\Config;
+
+require 'src/Exceptions/UnsupportedFormatException.php';
+require 'src/Exceptions/WriteException.php';
+require 'src/ConfigInterface.php';
+require 'src/AbstractConfig.php';
+require 'src/Config.php';
+require 'src/Record.php';
+require 'src/Writers/WriterInterface.php';
+require 'src/Writers/PhpWriter.php';
+
+$config = new Config;
+```
+
+## Usage
+
+### Making the configuration
+
+Configuration making is possible using `ConfigWriter\Config` class.
+
+```php
+$config = new Config;
+```
+
+It accepts two parameters, data and comment, and both are optional.
+Data parameter contains pre-set data for configuration and comment contains additional comment (or code) on top of the configuration file.
+
+```php
+$config = new Config(
+    [
+        'username' => 'user',
+        'password' => 'pass',
+    ],
+    <<<EOD
+/**
+ * The configuration file.
+ *
+ * It contains configuration data.
+ */
+EOD;
+);
+```
+
+### Adding records
+
+Records can be added using `ConfigWriter\Config::addRecord()` method.
+
+```php
+$config->addRecord('application', 'ConfigWriter');
+```
+
+They can also have comments, which will be generated in documentation.
+
+```php
+$config->addRecord('application', 'ConfigWriter', 'Application name');
+```
+
+### Adding sections
+
+Sections visually and functionally separate multiple records. They can be added using `ConfigWriter\Config::addSection()` method.
+
+```php
+$database = $config->addSection('database', [], 'Database settings');
+
+$database->addRecord('host', 'localhost', 'Database host');
+$database->addRecord('port', '3306', 'Database port');
+```
+
+They can also have pre-set data using second parameter.
+
+```php
+$config->addSection(
+    'database',
+    [
+        'host' => 'localhost',
+        'port' => '3306',
+    ],
+    'Database settings');
+```
+
+### Saving configuration
+
+You can save configuration using `ConfigWriter\Config::toString()`  or `ConfigWriter\Config::toFile()`.
+
+When saving to string, configuration writer is required, and when saving to file, writer will be automatically determined.
+
+```php
+$config->toString(new ConfigWriter\Writers\PhpWriter);
+$config->toFile('config.php');
+```
+
+Writers can also have specific options for writing.
+
+```php
+$config->toFile('config.php', new ConfigWriter\Writers\PhpWriter, ['indentation' => '	']);
+```
+
+The only supported writer is for PHP array, but more writers will be added later.
