We are now going to create a shopping cart module:
Log in to your PrestaShop control panel and click on the Modules tab. You should see the same window that you saw in the previous screenshot.
When you scroll down the list of modules, you will see the Cart block module. Just to the right of the description, click on the Install button (it is installed by default).
Now scroll back to the Cart block module. Notice the word in green. Click on Configure.
Here you have the option to select an Ajax cart. AJAX is a suite of technologies that enables some really cool and smooth web effects. Sounds like a good idea? Thought so. The reason you have the option to switch AJAX off is that some older templates that we will look at later in this chapter do not get along with AJAX, so you will need to switch it off. For now at least, I suggest leaving it on. Click on Save when you’re ready.
Go and have a look at your shop front. You should see a page similar...
