Default When to flash recovery?

I found this site on how to root my Touchpad:

and this one on how to install CM onto it:

But nothing mentions when/how to install CWM (or one of the ones listed below) as shown on the CM nightly page found below
-PhilZ Clockworkmod (non-touch)(will backup and restore in both cwm and twrp format)
-Milaq's ClockworkMod
-Flintman's TWRP

At what place would I flash the Recovery?
