Could you guys advise where to start learning how to make the theme fully supports WooCommerce plugin? Are there any requirements or checklist available too?
Your best bet is to purchase some best selling WooCommerce themes here and look at how they do things.
I guess you should buy a store and try to use any features.
I’m no expert on WooCommerce, but I try to provide people with basic integration for my themes. People seem to not really have any problems as long as the basic parts are in place.
So, the main thing you want to ensure is just that your theme is setup to not break on WooCommerce pages. In other words, you want your WooCommerce to fit in your theme’s wrapper, which by default is essentially WooCommerce slapped between your header.php and footer.php—this default behavior obviously breaks in many themes.
Here’s the article that lays out how you can do this with either using action hooks or creating a new template file in your theme:http://docs.woothemes.com/document/third-party-custom-theme-compatibility/
Also, make sure to see the very end of the article about declaring support. This is nice for buyers because they get scared when there’s a message at the top of the screen that says “Your theme does not support WooCommerce.”
From there, you’ll have basic support. If you’re looking to take things farther and make a true WooCommerce template, I think you’ll just want to get WooCommerce installed in your dev environment and just start going through styling how all the different WooCommerce features look with your theme.
Read the woocommerce documentation, surf the code ( this is the advantage of the open source )
don’t forget to use add_theme_support(‘woocommerce’);
