Welcome to the forums! It's a great place to ask questions, share experiences, and give feedback.
Another great resource is https://magento.com/technical-resources
, which includes documentation on much of Magento's standard features and functionality.
Additionally, you can view "known" issues with the Magento 2 platform on Github: https://github.com/magento/magento2/issues
You can learn about the forum guidelines here: https://community.magento.com/t5/News-Announcements/Guidelines-for-Using-the-Magento-Forums/m-p/1519...
...and if you ever get stuck, just ask a question, or reach out to @sherrie who oversees this forum.
Best of luck!
