What are the first steps in exploring Magento 2?
In addition to what Steve Johnson has written, I would add the following source..
First and foremost, I recommend you to read this eBook, it's like the Bible for all beginning Magento 2 developers:
https://www.packtpub.com/web-development/magento-2-developers-guide
Also, check these best Magento 2 blogs - here you'll learn about some aspects of Magento 2 development, that the official Magento documentation doesn't mention:
- https://firebearstudio.com/blog/category/magento-2
- http://inchoo.net/category/magento-2/
- http://www.ibnab.com/en/blog/magento-2
- http://alanstorm.com/category/magento-2
Also, you can find some useful info on Magento 2 in the official Magento blog:
- https://magento.com/blog/tag/magento-2
Also, I would like to know how the basic principles have been changed, I mean: catalog, products, quotes, carts. If someone can share the experience of migrating from M1 to M2 ( the popular issues and their solutions) it will be very useful and I will be highly grateful.
