I reported a bug on GitHub, now I'm asked for files, but there's no way to attach them to the raised issue (e.g. on Launchpad you can attach file to a bug report, but on GitHub there's only option to attach pictures).
I've read the issues section of the GitHub FAQ, but didn't find anything sufficiently illuminating. It seems like a novice user is implicitly directed by the site somewhere, but where?
Should I just create a repository and put all the requested snippets and output files there? Or should I just email the files to the project's maintainer? What I'm asking here boils down to this: what people do usually?
