If you have set the configuration, there are two steps left to take before you can add your products.
First create a Category for you products, and publish it!!
You should create a main categorie first , and then create subcategories in that categorie:
Categories are not automaticly published.
You can later on edit the description and name of the categorie, you can no longer change the categorie to be part of an other categorie.
You could do this within MySqlAdmin, but not within the component, you should then delete the categorie and create a new one under the categorie of your choise.
Then upload the pictures of you products.
If that is done, you can start adding products, since the product page needs a category and a picture, otherwise you can not save the page…
After adding the page, publish the product.
To acces the pages, you need to create a menu item pointing to the component, after that, you are ready to check if it all works..
p.s. page will be edited to provide more screenschots and detailed information.
