Anything that describes or acts on *this* repository now points here. Attribution to the upstream authors is deliberately left untouched. Functional, would otherwise misbehave on this fork: - Docker workflows pushed to a ghcr namespace this account cannot write to. - scripts/run_jmusicbot.sh auto-updated from arif-banai's releases, so it would have replaced this jar with the upstream one. - pom.xml scm/issueManagement/ciManagement described the upstream repo. - Removed .github/FUNDING.yml, which put a Sponsor button on this repo that funded arif-banai. Cosmetic: - Badges repointed; dropped the CircleCI, CodeFactor and Discord badges, which reported on services this fork is not registered with. - License badge now targets main rather than master. - Fixed the README header image: it was a float-right <img> that overlapped the note block, now centred above the title with alt text. - Refreshed the stale JMusicBot-0.6.2 jar name in the run examples. Left alone on purpose: copyright headers, pom.xml <developers>, the NOTICE and README credit tables, and the upstream commit provenance in docs/ARCHITECTURE.md.
