+# systemd-timer
+
+![Project time](https://waka.0xmax42.io/api/badge/0XMax42/interval:any/project:systemd-timer?label=Project%20time)
+
+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`: Zeitplan für den Timer (systemd `OnCalendar`)
+  - `--exec`: Auszuführendes Kommando (`ExecStart`)
+  - `--description`: Beschreibung für die Unit
+  - `--after`: `After=`-Abhängigkeiten in der Service-Unit
+  - `--environment`: Beliebige `Environment=KEY=VALUE` Einträge
+  - `--output`: Zielverzeichnis für die generierten Unit-Dateien
+  - `--run-as`: Setzt `User=` in der Service-Unit (nur systemweite Timer)
+  - `--home`: Setzt `Environment=HOME=…`
+  - `--cwd`: Arbeitsverzeichnis des Prozesses (`WorkingDirectory`)
+  - `--dry-run`: Gibt nur die generierten Inhalte aus, ohne sie zu schreiben
+- Getestet und typisiert mit **Deno** + **Cliffy**
+
+---
+
+## 🛠️ Installation
+
+
+Du kannst `systemd-timer` direkt per Shell-Skript installieren:
+
+```bash
+curl -fsSL https://git.0xmax42.io/maxp/systemd-timer/raw/branch/main/scripts/install.sh | sh
+```
+
+Das Skript erkennt automatisch deine Plattform (Linux `amd64` oder `arm64`) und installiert die passende Binary nach `/usr/local/bin`, sofern dies erlaubt ist (ggf. mit `sudo`).
+
+**Hinweis:**
+- Für die Installation ist eine funktionierende Internetverbindung notwendig.
+- Die Integrität der Binary wird mittels SHA256-Prüfsumme verifiziert.
+- Du kannst das Skript vor der Ausführung auch manuell inspizieren:
+
+```bash
+curl -fsSL https://git.0xmax42.io/maxp/systemd-timer/raw/branch/main/scripts/install.sh -o install.sh
+less install.sh
+```
+
+Weitere Optionen und manuelle Installationswege findest du unter [`scripts/install.sh`](scripts/install.sh).
+
+---
+
+## 📦 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.

 # systemd-timer
 
-Ein einfaches CLI-Tool zum schnellen Erzeugen von systemd `.service` und `.timer` Units – als Ersatz oder moderne Ergänzung zu klassischen `cron`-Jobs.
+- ![Project time](https://waka.0xmax42.io/api/badge/0XMax42/interval:any/project:systemd-timer?label=Project%20time)
+- [Deutsche Version dieser Readme](README.DE.md)
+
+A simple CLI tool for quickly generating systemd `.service` and `.timer` units — as a replacement or modern supplement to classic `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
+* Generates `.service` and `.timer` files via CLI
+* Supports `--user` timers (for `~/.config/systemd/user/`)
+* Optional logging (`StandardOutput/StandardError`)
+* Supports:
+  * `--calendar`: Timer schedule (systemd `OnCalendar`)
+  * `--exec`: Command to execute (`ExecStart`)
+  * `--description`: Description for the unit
+  * `--after`: `After=` dependencies in the service unit
+  * `--environment`: Arbitrary `Environment=KEY=VALUE` entries
+  * `--output`: Target directory for the generated unit files
+  * `--run-as`: Sets `User=` in the service unit (only for system-level timers)
+  * `--home`: Sets `Environment=HOME=…`
+  * `--cwd`: Working directory for the process (`WorkingDirectory`)
+  * `--dry-run`: Outputs unit content without writing to disk
+* Tested and fully typed with **Deno** + **Cliffy**
 
 ---
 
 ## 🛠️ Installation
 
-```bash
-git clone https://git.0xmax42.io/maxp/systemd-timer.git
-cd systemd-timer
-deno task build
+You can install `systemd-timer` directly via shell script:
 
-# Binary liegt nun unter ./systemd-timer
-./systemd-timer --help
+```bash
+curl -fsSL https://git.0xmax42.io/maxp/systemd-timer/raw/branch/main/scripts/install.sh | sh
 ```
 
+The script automatically detects your platform (Linux `amd64` or `arm64`) and installs the appropriate binary to `/usr/local/bin`, if permitted (possibly using `sudo`).
+
+**Note:**
+
+* A working internet connection is required for installation.
+* The integrity of the binary is verified using a SHA256 checksum.
+* You can manually inspect the script before execution:
+
+```bash
+curl -fsSL https://git.0xmax42.io/maxp/systemd-timer/raw/branch/main/scripts/install.sh -o install.sh
+less install.sh
+```
+
+Additional options and manual installation methods are available under [`scripts/install.sh`](scripts/install.sh).
