Change logo how-to

Good morning,
I need to change something simple, a logo at the John theme but I am unable to accomplish this... very odd.
I thought it is changed through Template Options but cannot find it.
Second I tried to upload a logo.png in images directory to themes/John-Child/images/ but still no luck.

Is there a manual for this seem to be simple task?

Thanks!

Hello,

Please navigate to Template Options -> Theme Branding tab, within "Theme logo type" option you can select "Image logo" and upload your image.

Great Piotr! Thank you.
