# Requirements - Stockline 1.x documentation

> The WordPress, WooCommerce and PHP versions Stockline needs, and the themes and store setups it works with.

- **WordPress** 6.5 or later (tested up to 7.1)
- **WooCommerce** 8.2 or later (tested up to 11.1), active; WordPress won't activate Stockline without it
- **PHP** 7.4 or later

## What it works with

- **Classic themes and block themes.** Stockline changes the stock line that WooCommerce itself builds, which both kinds of theme show on the product page. In block themes that's the **Add to Cart with Options** block (called Add to Cart Form in older WooCommerce versions), which shows the stock line above the quantity and button.
- **Simple and variable products.** On a variable product, the stock line changes as shoppers pick options, following each variation's own stock.
- **High-Performance Order Storage (HPOS)** and the block-based cart and checkout. Stockline doesn't touch orders, the cart or the checkout, and declares itself compatible with both.
- **Your theme's styling.** The stock line keeps WooCommerce's own `stock`, `in-stock`, `out-of-stock` and `available-on-backorder` classes, so CSS written for them still applies.

## Where the stock line appears

Stockline changes the stock line wherever WooCommerce shows it: on single product pages, including the line that appears when a shopper picks a variation. WooCommerce doesn't show stock in shop and category listings, the cart or the checkout, so neither does Stockline.

If you show a product somewhere else, such as a Single Product block on a landing page, the message appears there too, but Stockline's small stylesheet only loads on product pages by default. See **Troubleshooting** for the one-line fix.

## Nothing else to set up

Stockline adds no database tables, scheduled tasks or external requests. Its settings are a handful of WordPress options, and it reads stock from WooCommerce as it is.
