-This little SATA board is a convenient and compact way to add up to 5 SATA drives to a Raspberry Pi, either via a CM4 carrier board that has a built-in full-size (80mm) M.2 slot, or via a PCI Express x1 to M.2 adapter card.
+This little SATA board is a convenient and compact way to add up to 5 SATA drives (there's also a 6-port version) to a Raspberry Pi, either via a CM4 carrier board that has a built-in full-size (80mm) M.2 slot, or via a PCI Express x1 to M.2 adapter card.
 
 Since mid-2021, [SATA support is built into the Raspberry Pi kernel](https://www.jeffgeerling.com/blog/2021/raspberry-pi-os-now-has-sata-support-built), so assuming you have updated to the latest version (`sudo apt upgrade -y`), this card should work out of the box.
+
+On the Pi 5, you may need to add the following options in your `/boot/firmware/config.txt` for better compatibility with this and other SATA controllers:
+
+```
+dtoverlay=pciex1-compat-pi5,no-mip
+dtoverlay=pcie-32bit-dma-pi5
