Custom Logos

[Ryo96]

So, I was following a couple of tutorial about import custom logos with Unity but there are some steps that I don't Understand.
Like
- Import your logo into Unity. Do I have to create a new empty project or do I have to use the workshop template?
- Export the AssetBundle. Ho to do it? I don't find the button "Build"or "Export" for the Asset Bundles.
Or else, Is there an easier way? Because these tutorials are 2 or 3 years old, maybe there's another way. Thank you
