Integrate into my site's theme

Hi @mrpmorris,
In general, any theme should work fine with jigoshop.
If it seems to be unstyled – then here is info what to do: https://forum.jigoshop.com/kb/customize-jigoshop/wrap-your-themes-content-for-jigoshop
If that won’t help – you can either let our developer support you (paid) or try using one of checked jigoshop-optimised themes (list on https://www.jigoshop.com)
