Theme not showing

[ActionJay]

Been trying for half a day now to make my magento theme show up... without luck... It is not displayed in Content/Themes. What have I missed/need to do?

Created a bunch of folders and files

www/magento/pub/static/frontend/MyPackage/mytheme2 
Magento_Theme  (layout/default.xml)
media  (has a preview img)
web (has empty css & image & js folders)
composer.json
registration.php
theme.xml

Theme.xml

<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd">
<title>MyPackage mytheme2</title>
<parent>Magento/luma</parent>
<media>
<preview_image>media/preview.jpg</preview_image>
</media>
</theme>

registration.php

<?php
/**

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::THEME,
    'frontend/MyPackage/mytheme2',
    __DIR__
);

composer.json

{
    "name": "MyPackage/mytheme2",
    "description": "N/A",
    "require": {
        "php": "~5.5.0|~5.6.0|~7.0.0",
        "magento/theme-frontend-luma": "~100.0",
        "magento/framework": "~100.0"
    },
    "type": "magento2-theme",
    "version": "1.0.0",
    "license": [
        "OSL-3.0",
        "AFL-3.0"
    ],
    "autoload": {
        "files": [ "registration.php" ]
    }
}

Have you done?

bin/magento setup:upgrade
bin/magento cache:flush

-> www/magento/pub/static/frontend/MyPackage/mytheme2

You shouldn't create a theme directly in pub/static directly as it is MEANT to be for STATIC FILES only. Magento compiler is used for this. You should either create your theme in app/frontend or vendor/{vendorName}/mytheme2 directory. 

Once you have created the theme in the right folder, run the following: 

php magento cache:clear

php magento setup:upgrade

php magento setup:di:compile

The following will deploy your theme to pub/static directory: 

php magento setup:static-content:deploy --theme {vendorName}/myTheme2

 Let me know if that helps.
