[Plugin: WordPress SEO by Yoast] – Meta Descriptions

Enable Meta Descriptions

I am using Elegant Theme’s Polished theme as well as Yoast’s WordPress SEO plugin which I want to take priority.

Which ET option should I select? Enable or disable?

WP>Appearance>Polished Theme Options>epanel>SEO>Index page> Enable meta descriptions

Said differently…
If I enable this within the theme’s settings, will the plugin’s settings work so that I can enter my own custom text for each page?
Does this have to be enabled in ET in order for meta descriptions to operate at all, or is this just for the theme to control meta descriptions?

TIA
