 In the [[GNU Radio Benchmark example|first tutorial]] we introduced the way to construct a CorteXlab "task" given a ready-made GNU Radio script.

 The purpose of this tutorial is to execute an OFDM transmission between two USRP nodes. One node will be the transmitter and the other one will be the receiver. Instead of starting from an empty project, we are going to use the GNU Radio examples for an OFDM transmitter and receiver.
-Let us start by copying the files ''tx\_ofdm.grc'' and ''rx\_ofdm.grc'' located in ''$path\_to\_gnuradio/examples/digital/ofdm'' to a new folder of your choice. This folder will be your task folder.
+Let us start by copying the files ''tx\_ofdm.grc'' and ''rx\_ofdm.grc'' located in ''<path\_to\_gnuradio>/examples/digital/ofdm'' to a new folder of your choice. This folder will be your task folder. //(Important note: <path\_to\_gnuradio> varies depending upon the way you are using GNURadio: If you have installed GNURadio on your workstation, you know where you choose to install it. If using the GNURadio instance which is part of CorteXlab toolchain on airlock, then the exact location is: ''/cortexlab/toolchains/current/share/gnuradio/examples/digital/ofdm/'')
+//
 As you can guess ''tx\_ofdm.grc'' will be used for the OFDM transmitter and ''rx\_ofdm.grc'' for the OFDM receiver.
