TP-Link mr3040 v 2.3 : what tutorial to install PirateBox ?

Hello, I bought a TP-Link mr3040 v 2.3

What tutorial should I follow to install (recent version of) PirateBox onto ? :S

According [wiki.openwrt.org] : since 2014 OpenWRT is confirmed to work onto.


I found this tutorial, but it was write in 2012 : [www.disk91.com]

Note : I am a newbie about Linux and PirateBox making.
