+# ansible-role-radarr
+
+Installs Radarr from GitHub releases on Linux. The role detects the current
+architecture and downloads the matching binary. It is idempotent: re-running
+the role only downloads and extracts if the installed version differs.
+
+The service user and group must be created beforehand (e.g. via a users role).
+
+## Requirements
+
+- Ansible >= 2.14
+- `sqlite3` package on the target host
+
+## Role Variables
+
+| Variable | Default | Description |
+|---|---|---|
+| `radarr_version` | `""` | Version to install (empty = latest) |
+| `radarr_user` | `radarr` | System user to run Radarr |
+| `radarr_group` | `radarr` | System group to run Radarr |
+| `radarr_install_dir` | `/opt/radarr` | Binary installation directory |
+| `radarr_data_dir` | `/var/lib/radarr` | Data and config directory |
+| `radarr_service_enabled` | `true` | Enable service at boot |
+| `radarr_service_state` | `started` | Service state after installation |
+
+## Example Playbook
+
+```yaml
+- hosts: servers
+  roles:
+    - role: ansible-role-radarr
+      vars:
+        radarr_user: radarr
+        radarr_group: radarr
