Some algorithms, like `share` are not included in all docs & the README

It would be best to advertise it everywhere (not sure what places that are). At least the README isn't fully up-to-date, leading to believe newer features aren't there yet

Start by reading the README and searching the repository documentation for the `share` algorithm and other algorithm listings. Identify every relevant place where algorithms are advertised, then update the incomplete listings so `share` and the newer features are consistently represented throughout the documentation.
