+# systemd-timer
+
+Ein einfaches CLI-Tool zum schnellen Erzeugen von systemd `.service` und `.timer` Units – als Ersatz oder moderne Ergänzung zu klassischen `cron`-Jobs.
+
+---
+
+## 🚀 Features
+
+- Erzeugt `.service` und `.timer` Dateien per CLI
+- Unterstützt `--user` Timer (für `~/.config/systemd/user/`)
+- Optionales Logging (`StandardOutput/StandardError`)
+- Unterstützt:
+  - `--calendar`
+  - `--exec`
+  - `--after`
+  - `--environment`
+  - `--output`
+  - `--dry-run`
+- Getestet und typisiert mit Deno + Cliffy
+
+---
+
+## 🛠️ Installation
+
+```bash
+git clone https://git.0xmax42.io/maxp/systemd-timer.git
+cd systemd-timer
+deno task build
+
+# Binary liegt nun unter ./systemd-timer
+./systemd-timer --help
+```
+
+---
+
+## 📦 Beispiel
+
+```bash
+./systemd-timer create \
+  --exec "/usr/local/bin/backup.sh" \
+  --calendar "Mon..Fri 02:00" \
+  --description "Backup Job" \
+  --user \
+  --logfile "/var/log/backup.log"
+```
+
+Erzeugt:
+- `~/.config/systemd/user/backup.service`
+- `~/.config/systemd/user/backup.timer`
+
+Anschließend aktivieren:
+
+```bash
+systemctl --user daemon-reload
+systemctl --user enable --now backup.timer
+```
+
+---
+
+## 🧪 Tests ausführen
+
+```bash
+deno task test
+```
+
+---
+
+## 🧰 Entwickeln
+
+```bash
+deno task start create --exec "/bin/true" --calendar "daily" --dry-run
+```
+
+---
+
+## 🔒 Rechte / Flags
+
+Das Tool benötigt beim Ausführen bzw. Kompilieren:
+
+- `--allow-env` (für `$HOME`)
+- `--allow-write` (zum Schreiben von `.service`/`.timer`)
+
+Beim Entwickeln wird meist `-A` (allow all) verwendet.
