Setting Up Recast and other Graphs

Hi …
I have been trying to figure out, Recast Graph but don’t really understand how to set it up …
I did work out Grid graph thanks to the tutorial getting started and got some good results… but I have no idea how to set up any other graph… their settings look different and confusing… and in particular recast graph… is there any sett up guide/tutorial on how to set it up properly, hopefully step by step thanks
