composer install

Create a database, import the dump.sql, adjust the database credentials in public/typo3conf/LocalConfiguration.php.

Setup the site so you can browse it with a web browser. php -S localhost:8080 -t public should suffice. Of course you are free to setup apache/nginx. Your decision, your responsibility.

Once you setup the site and open a browser, you see the demo plugin that shows a form which is powered by symfony/form, along with other symfony components for validation, twig integration, csrf support, xlf readers and so on.

• Backend login: admin -> password
• Install tool password: password

This is just a small tech demo which demonstrates that it's quite easy to build forms with symfony components. I do not intend to create any form extension as a competitor to any other form extension. It's just that: If you are a developer and need a quick and solid solution for simple forms that don't need to be managed by editors, this might be just the right solution for you.

Again: Your decision, your responsibility. :)
