You install it like any other plugin, with the bonus of a guided setup wizard.
Step by step
- Go to Plugins → Add New, search for « WooCommerce », then install and activate it.
- A setup wizard starts: enter your store address, your industry and the type of products you sell.
- WooCommerce automatically creates the pages you need: Shop, Cart, Checkout and My Account.
Good to know: those four pages are essential. Never delete them — they are what makes the whole buying journey work.
