 # Query
 
 A query builder/abstraction layer.
+
+## Databases Supported
+	
+	* Firebird
+	* MySQL
+	* PostgreSQL
+	* SQLite
+	* Others, via ODBC
+	
+## Requirements
+	* Pdo extensions for the databases you wish to use (unless it's Firebird, in which case, the interbase extension is required)
+	
+	
+## Connecting
+
+Create a connection array or object similar to this:
+
+	<?php
+	
+	$params = array(
+		'type' => 'mysql',
+		'host' => 'localhost',
+		'user' => 'root',
+		'pass' => '',
+		'port' => '3306',
+		'database' => 'test_db',
+		
+		// Only required
+		// SQLite or Firebird
+		'file' => '/path/to/db/file',
+	);
+	
+	$db = new Query_Builder($params);
+
+The parameters required depend on the database. 
+
+### Running Queries
+Query uses the same interface as CodeIgniter's [Active Record class](http://codeigniter.com/user_guide/database/active_record.html). However, it does not implement the `select_` methods, `count_all_results`, or `count_all`.
+
+To retreive the results of a query, use the PDO methods `fetch` and `fetchAll`.
+
+	$query = $this->db->get('table_name');
+	
+	$results = $query->fetchAll(PDO::FETCH_ASSOC);
