How to install a Module Extension

Hi - I’m new to the Vassal system and have a question that is probably blindingly obvious. Nonetheless the solution escapes me.

I cannot figure out how to install the Band of Brothers: Ghost Squadron extension. I have the Band of Brothers: Screaming Eagles base module installed and working great. I’m hoping someone can please point me in the right direction. Sorry if I’m wasting everyone’s time. I’ve searched through the wiki and the forums but just can’t seem to find the answer to this.

Thanks so much in advance for any response.

In the main launcher, right-click the module and Add Extension, then browse to the vmdx file.

Thank you so much! I knew it had to be something ridiculously easy to do. Thanks for the help!
