 .Sh DESCRIPTION
 NVM Express (NVMe) is a storage protocol standard, for SSDs and other
 high-speed storage devices over PCI Express.
+.Pp
+.Ss logpage
+The logpage command knows how to print log pages of various types.
+It also knows about vendor specific log pages from hgst/wdc and intel.
+Page 0xc1 for hgst/wdc contains the advanced smart information about
+the drive.
+Page 0xc1 is read latency stats for intel.
+Page 0xc2 is write latency stats for intel.
+Page 0xc5 is temperature stats for intel.
+Page 0xca is advanced smart information for intel.
+.Ss wdc
+The various wdc command retrieve log data from the wdc/hgst drives.
+The
+.Fl o
+flag specifies a path template to use to output the files.
+Each file takes the path template (which defaults to nothing), appends
+the drive's serial number and the type of dump it is followed
+by .bin.
+These logs must be sent to the vendor for analysis.
+This tool only provides a way to extract them.
