+# BadNews: Matrix Bot, Bringer of Bad News
+
+## What is this?
+
+`BadNews` is a [Matrix](https://matrix.org) bot, watching your systemd/journald
+logs, and reporting bad news to you.
+
+## Why?
+
+A mix of wanting to toy around with the [matrix_sdk
+crate](https://github.com/matrix-org/matrix-rust-sdk) and getting some simple
+alerts from my hosted services.
+
+## Setup
+
+Write up a configuration file at `config.yaml`:
+
+```yaml
+homeserver: "https://matrix.example.net"
+username: "bad-news"
+password: "matrix password for user bad-news"
+state_dir: "state/"
+room_id: "!DeaDbEef:example.net"
+units:
+  - name: nginx.service
+    filter: "\\[warn\\] .*"
+```
+
+Then run the bot:
+
+``` sh
+cargo run -- --config config.yaml
+```
+
+## Contributing
+
+I accept contributions via [GitHub](https://github.com/alarsyo/bad-news) Pull
+Requests and [GitLab](https://gitlab.com/alarsyo/bad-news) Merge Requests.
+
+### Sending patches by mail
+You can also send patches to
+[~alarsyo/patches@lists.sr.ht](https://lists.sr.ht/~alarsyo/patches) with the
+prefix `PATCH bad-news`.
+
+You can use the following commands to set up `git` appropriately;
+
+``` sh
+git config sendemail.to '~alarsyo/patches@lists.sr.ht'
+git config format.subjectPrefix 'PATCH bad-news'
+```
