-The CeroWrt router firmware project has largely eliminated the problem of *bufferbloat* on Ethernet for home routers. 
+This is a set of scripts (sometimes also called "Openscripts") that configure and measure (and improve) latency in home routers (and everywhere else!) These scripts include:
-This firmware makes a huge difference for wireless, too, although there's still more work to be done.
-The symptoms of bufferbloat give people cause to complain, "the Internet feels slow today." 
-The techniques that the CeroWrt team have proved out are being widely adopted across 
-the Internet to make everyone's network performance better.
 
-This is a set of scripts (sometimes also called "Ceroscripts") that we use to measure (and improve) latency in home routers (and everywhere else!) 
+* Script to configure the OpenWrt router consistently after flashing factory firmware.

-These scripts include:
 
 * Scripts that measure the performance of your router or offer load to the network for testing.
 
-* Script to configure the CeroWrt router consistently after flashing factory firmware.
-
 * Script to set up a IPv6 6-in-4 tunnel to TunnelBroker.net.
 
-* Script to collect troubleshooting information that helps us diagnose problems in the CeroWrt distribution.
+* Script to collect troubleshooting information that helps us diagnose problems in the OpenWrt distribution.
 
-These scripts are bundled into CeroWrt 3.10.44-3 and newer as the 'cerowrtscripts' package, saved in the `/usr/lib/CeroWrtScripts` directory.
+These scripts can be saved in the `/usr/lib/OpenWrtScripts` directory. They were cloned from the similar CeroWrtScripts at https://github.com/richb-hanover/CeroWrtScripts
-To get the newest versions, you can use `opkg update; opkg upgrade`
-
-If the scripts are not built into your version of CeroWrt, it is safe to put them in that CeroWrtScripts directory.
