I am trying to animate calligraphy using this method: https://css-tricks.com/animate-calligraphy-with-svg/
It's so cool that someone already got it working and shared their link on stack overflow (click the first link of the post): Animate calligraphy using image-file instead of SVG
But I'm a total beginner and don't know where they got the crazy numbers for their path: "<path d="M 92.81613,118.88531.......". So far I just added some paths in the characters to make the mask paths. Can someone please explain the tutorial (first link above) for me as someone who has zero experience in working with SVG in Inkscape and animating them? Thank you!
