I'm really new to concrete5 and I have searched the forum for an answer to this, but just not getting it.

How do I get a custom block to show up as "Awaiting Installation" and/or to be available for selection from a page in edit mode?

I need to build a custom block so I cloned the HTML block and renamed the folder to symas_test. I put the folder in /myWeb/packages/symas_test/blocks/ and put a controller.php in the symas_test directory. I edited the controller.php based on some sample code I found, but nowhere does it suggest how to get my concrete5 web to "see" this new block.

What am I missing here?

<?php
defined('C5_EXECUTE') or die(_("Access Denied."));
class Symas_Test extends Package {
protected $pkgHandle = 'iframe';
protected $appVersionRequired = '5.2.0';
protected $pkgVersion = '1.0';
public function getPackageDescription() {
return t("Insert a Symas Test.");
}
public function getPackageName() {
return t("Iframe");
}
public function install() {
$pkg = parent::install();
// install block
BlockType::installBlockTypeFromPackage('symas_test', $pkg);
}
}
