		<h3>
		 But I'm lazy!!
		</h3>
		<p>Since Phalcon 0.3.2 there's a new nifty feature called "developer tools".</p>
<pre class="prettyprint">
phalcon create-project candy-shop
phalcon create-controller --name User

phalcon create-model --table-name users --gen-getters-setters

<p>create-model allows you to modify database table between code generations (next code generation will not remove your code, just modify needed parts).</p>

<pre class="prettyprint">
CREATE TABLE users(
  id int,
  name varchar(255)

phalcon create-model --table-name users

<h3>Drawbacks</h3>
<ul>
	<li>young
	<li>don't use it for mission critical apps. yet.
	<li>no DI (Symfony anyone?)
	<li>limited feature set
	<li>hard to debug
	<li>code completion is tricky - even in your beloved PHPStorm (need to use <a href="http://phalcon.uservoice.com/forums/154026-general/suggestions/2724445-code-completion-to-major-ide-s-based-on-stub-files">stub</a> files)

		<h3>
		  Bonus: Q&amp;A after speech
		</h3>
		<p>
		<b>Q: What do you think about Phalcon future?</b> <br />
		A: I believe that as far as Phalcon is a great project itself, it's mission is rather to spread a brand new technical tought than become a new ZF.
		</p>
		<p>
		<b>Q: Does Phalcon use PDO?</b> <br />
		A:  <i>"From PDO to native drivers, Phalcon encapsulate the specific details of each database engine in dialects. Those provide common functions and SQL generator to adapters."</i><br /> ATM of writing, there's only MySQL dialect availble, which doesn't mean you cannot use PDO or <a href="http://php.net/manual/en/book.mongo.php">mongo</a> while developing in Phalcon.
		
		</p>
		<p><b>Q: Do you know ANY project that switched to Phalcon in order to improve performance?</b> <br />
		A: Why don't you read the drawbacks slide?
		</p>
		
		<p><b>Q: Can you use SQLite with Phalcon?</b> <br />
		A: Yes you can, using PDO_SQLITE, as Phalcon does not provide yet Phalcon_Db_Dialect_Sqlite class. 
		</p>
		<p>
		<b>Q: Does Phalcon use under the hood PDO ex. in  Phalcon_Db_Dialect_Mysql?</b> <br />
		A: As since PHP 5.4 there's mysqlnd under the hood, Phalcon uses <a href="http://dev.mysql.com/doc/refman/5.5/en/apis-php-mysql.html">mysql</a> extension.
		</p>
		
		<p><b>Q: What versions of PHP does Phalcon support?</b><br />
		A: >=5.3
