Resonar Theme Customisation

[ Moved to the Fixing WordPress sub-forum. Please do not use Developing with WordPress for these topics. ]

Hey there,

I recently exported a customer’s website from ‘wordpress.com’ and imported it into ‘wordpress.org’.
The adopted theme is ‘Resonar’. Under the ‘Site Identity’ option in ‘wordpress.com’ was an option to have a Logo, which is placed by default to the upper left of the page, and is adjacent to the top menu.
The logo option is not available in ‘wordpress.org’ for the same theme.
Has anyone got any idea how I can display a Logo on the top left of the page; padding would be cool too so as to accurately position the Logo.

Any help would be greatly appreciated, thank you.
