Magento code is awesome – just awesome that you’ll be lost even after reading hundreds of forum posts, wikis and blogs. This is what happen with me for the first time.
I am still novice for Magento. Here’s few things that I discovered myself while learning Magento.
Magento Installation
I didn’t find Magento running in localhost so you have to create host address. If you are linux guy, this must not be tough for you. Window user, create host that map to your local PC (If you don’t know window host file, fallow this link). Now you can install Magento with full host address something look like http://magentohost.com
You can rarely find documentation about Magento. Luckily you have here some:
While installing Magento do not modify default options, except SEO friendly. I have lot of trouble when I modified default options.
Magento Theme Development
Magento is built on Zend Framework, so understanding Zend MVC will be very helpful to develop Magento Theme. You can fallow this link (http://www.magentocommerce.com/design_guide) to learn about Magento Theme Development.
Magento Store Managing
If you are store owner and want to manage catalog effectively, I suggest to buy Magento User Guide http://www.magentocommerce.com/support/magento-user-guide-book. If you do not study guide, I bet you that you’ll be unable to add products and sale them.
Other resources, you can sign up for Magento Community and participate on forum and chat.
Update: Some tips on code about showing images on grid.
