hey @konstantinkoniukov, the size of the SVG you added seemed to be causing the build to fail, which I've resolved by wrapping it in <img> tags. Seems to work, but feel free to edit if you'd rather just replace it with the PNG you added (since this is essentially what it's reduced to now anyway, if I understand correctly). Other than that, if you resolve the two minor corrections (we use sentence case for subheadings), then I can merge!

Hey @jlwllmr! I've changed the subheadings. If we're good to go, let's merge!
