-Netfilter provides several accounting mechanisms:
+Netfilter provides three accounting mechanisms:
 
-* flow-based accouting through ctnetlink
+* flow-based accounting through ctnetlink
 * packet-based accounting through NFLOG
+* extended accounting through nfacct (since Linux 3.3)
 
-This library contains the user-space part of a third new mechanism that
-provides area-based accounting.
-
-You have to get the kernel part from:
-
- git clone -b nf git://1984.lsi.us.es/net
-
-Or you can obtain the patches that apply to 3.2-rc from the cgit interface:
-
- http:/1984.lsi.us.es/git
-
-Make sure you compile the kernel with NFNETLINK_ACCT and XT_TARGET_NFACCT
-support.
+The libnetfilter_acct library provides the programming interface (API)
+for the extended accounting infrastructure.

+This mechanism allows you to create one accounting object:

 Then, you can use it in iptables:
 
- # iptables -I INPUT -p tcp --dport 80 -j NFACCT --nfacct-name http-traffic
- # iptables -I OUTPUT -p tcp --sport 80 -j NFACCT --nfacct-name http-traffic

 You can obtain the counters via libnetfilter_acct:
 
  libnetfilter_acct/examples# ./nfacct-get
  http-traffic = { pkts = 000000061152,   bytes = 000082999936 };
 
-You can perform different actions like dumping the counters and reset them.
+To enable the extended accounting infrastructure in kernel-space, make sure
+you enable NFNETLINK_ACCT and XT_MATCH_NFACCT config options in your Linux
+kernel.
