-== About NVMe
+== About NVMe ==
 VM Express, NVMe, or Non-Volatile Memory Host Controller Interface Specification (NVMHCI), is a logical device interface specification for accessing non-volatile storage media attached via PCI Express (PCIe) bus. Some links related to the standard and vendor-specific implementations provided below:
 - [http://nvmexpress.org/specifications/ Official specifications]
 - [http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/ssd-dc-p3608-spec.pdf Intel NVMe documentation] with  Intel-specific log pages (CAh, C5h, DDh, C1h/C2h).
 - [http://ocz.com/enterprise/download/guides/ZDrive_6000_Series_Datasheet.pdf OCZ Z-Drive] specification, with vendor-specific smart log page (E0h)
+== Smartmontools NVMe support ==
+Smartmontools supports NVMe starting from from version 6.5. Please note, that currently NVMe support is considered as experimental. Currently implemented features:
+- Basic information about controller name, firmware, capacity
+- SMART overall-health self-assessment test result and warnings (`smartctl -H`)
+- NVMe SMART attributes (`smartctl -A`)
+- NVMe error log (`smartctl -l error`)
+- Ability to fetch any nvme log (`smartctl -l nvmelog,N,SIZE`)
+- Initial smartd support
+
+Currently NVMe support is implemented on Linux, Windows and FreeBSD. Details about supported version/driver combinations are provided in the next section.
