Hey @iboonox, thanks again for your great work! Looks like you still need to sign the Linux foundation CLA, let me know if you encounter problems here. I just saw that everything is good now.

I wonder if we should merge the PNG files into the repository. They are binary files and those do not play well with git (everybody needs to download all revisions when cloning a repo). Given that the SVG files are superior vector graphics and display the same, I see no reason why we should also add the PNGs. WDYT?

Thanks a lot this makes me so happy! 💕

We could probably minify, but it’s ok.
Do you mind sending src files for future maintainers later on?

I think PNG is fine for now. Especially for ease of use in blog posts etc, I suspect they'll be needed.

PNGs are also easier to work with, e.g. people can easily mash it up with other pictures, or resize etc.
