Hi Morane,
in addition of this section of the devel documentation :
https://docs.softwareheritage.org/devel/swh-model/persistent-identifiers.html?highlight=shwid#computing
https://docs.softwareheritage.org/devel/swh-model/cli.html#command-line-interface
we talked about creating a video on how to locally compute a SWHID.
Thanks by advance for your help !
