Getting on board of PrestaShop
Since version 18.104.22.168 of PrestaShop, any new installation has the OnBoarding module activated by default. That module has been built from the ground up to help new users quickly understand the way the back-office works, taking them from basic customization to the shop's launch, with steps covering adding a product to the catalog, configuring the shop's payment methods, and choose the default shipping options. All this is done using a playful interface.
If you already know your way around the PrestaShop administration panel, you should probably disable that module:
How the module works
The module's interface cannot be missed: it the first thing you'll see at the top of each and every page of the back-office, before the page's own content.
Clicking the "Let's start!" button launches the whole process – which can be interrupted at any time, and finished later on. That process is shared between a window which appears on top of the back-office interface, which will give you instructions to follow, and the main interface itself, where you are expected to follow those instructions.
Step 1: customizing your shop
The first step helps you customize your shop, in order to make it your own. This is done by installing a new theme and uploading your brand's logo.
When you are done with customizing your shop, click on the module's "I'm done, take me to the next step" button.
Step 2: Adding products to your catalog
The second step takes you to the heart of your shop: the products you sell.
When you are done with creating products, click on the module's "I'm done, take me to the next step" button.
Step 3: Setting up your payment methods
The third step is an essential one: if you do not set your payment methods, you will NOT receive payment for your products sold!
When you are done with setting up your payment methods, click on the module's "I'm done, take me to the next step" button.
Step 4: Set up your shipping methods
The fourth step is also an essential one: if you do not set your shipping options, you have no way to make customers pay for shipping. If you are only selling digital products (PDF, etc.), then it makes sense not to have a shipping partner, but if you do sell real products, you have to indicate who your shipping partner is.
When you are done with setting up your shipping methods, click on the module's "I'm done, take me to the next step" button.
You're (mostly) done!
You have gone through all the essential steps in configuring your shop. There are many others, but those are necessary for selling on the Internet.
