Getting help

A question about running a node, joining a pool, lending a graphics card or using the desktop app: ask in Discussions, Q&A. Someone who has run into it before may answer, and the answer stays for the next person.
Something broken: open an issue with what you did, what happened, and the node's output around it.
A vulnerability: report it privately, as SECURITY.md says, not in public.

Before asking, Using Sisyphus walks through the desktop app, and apps/sisyphusd/README.md through running nodes.

Sisyphus is an early prototype made by two people in the open. There is no paid support, and an answer may take a day or two.
