I don’t have any specific link to share, but the bitmap tracing features in Inkscape have been working fine for me when I had to convert an image into an SVG.
For example for this I used the latest Inkscape 1.0 (beta), it has a splendid “Autotrace” feature.
Most of the time, it’s as simple as opening Inkscape, import your bitmap, then go to the “Path” menu and select “Trace bitmap”, then play around with the various tracing modes/thresholds to get the result you want, or close.
Sometimes a little manual touch up is required. It all depends on the input image (a sharp/clean bitmap with lots of contrast will probably work magically, a dirty/noisy bitmap will be more difficult to vectorize)
