problem opening audacity

I am running on mac os 10 version 10.9.5 and recently downloaded Audacity 2.0.6 dmg. When I attempt to open the software, a pop up shows “audacity” can not open because the identity of the developer cannot be confirmed. What can I do get around this barrier

This is explained in “Install.txt” that should be in the same folder as the Audacity application. Please right-click or control-click over, choose “Open”, then in the dialogue that appears, choose “Open”.
