Change Logo in learn2

Although I am knpwledge of html and php I am new to Grav, markdown and twig but am trying to get my head round it.
I’m using the Learn2 skeleton and want to puit my own logo in place of the default GRAV svg, cannot seem to find where its specified, i.e. how I change it. I guess its pulling it in from the first 3 lines of logo.html.twig but cannot work out how to change it.
Your help is appreciated.
PS Grav is awesome.

the best way is to generate ‘child theme’ with learn2 theme via DevTools plugin – :: after which you replace the logo in the image subdirectory of your new theme.
