NXOS vs IOS command reference -quality of the doc going down ?

Hi guys

Am I missing something here? Is there a better command refercence for NXOS? Please compare https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_bgp/command/irg-cr-book/bgp-c1.html#wp4282305997

with the NXOS corresponding page
