-Effect v4 rewrite of `git-agent`, using an Effect CLI structure and supporting
-both Git and Jujutsu (`jj`) repositories.
+`ai-commit` is the TypeScript / Effect port of the original Go-based
+`git-agent`, built with an Effect CLI structure and supporting both Git and
+Jujutsu (`jj`) repositories.
+
+## Demo

+## Acknowledgements

+[`GitAgentHQ/git-agent-cli`](https://github.com/GitAgentHQ/git-agent-cli).
+This project is an independent TypeScript / Effect re-port of that work. It is
+not affiliated with, maintained by, or endorsed by GitAgentHQ.
