Meta Tag Description

[5queezer]

Thanks for this nice theme, I like it!

I noticed that the description meta tag doesn't work. In your seo_schema.html:3 it is stated that
<meta itemprop="description" content="{{ if .Description }}{{ .Description }}{{ else }}{{if .IsPage}}{{ .Summary }}{{ end }}{{ end }}">

But my compiled theme always shows an empty content. The same is the case with the twitter and og meta tags.
<meta itemprop="description" content="">

In config.toml in the hugo root directory this setting is set:
description = "My great website bla bla..."

I could not fix the error. Please help.
Kind Regards,
Christian
