+      Spencer is a lightweight real-time server monitoring dashboard with a modern UI.
+
+      It provides live metrics for CPU (aggregate and per-core), memory, disk, network (per-interface), temperature sensors, GPU (NVIDIA/AMD), and running processes — all in a single-page app with drag-and-drop layout, resizable widgets, and 60 fps sparkline charts.
+
+      Features include multiple themes (dark/light with accent color variants), PWA support (installable as a standalone app), configurable UI scale, and a widget visibility manager. All data is served by a Go backend using gopsutil and requires no cloud dependencies — fully self-hosted.
+
+      Note: Temperature sensors and GPU monitoring require native Linux (not available inside Docker Desktop on macOS/Windows).

+  tips:
+    before_install:
+      en_us: >
+        Spencer requires access to host system metrics. The volume mounts
+        (/proc, /sys, /dev, /) and HOST_* environment variables are required
+        for full functionality. Temperature sensors and GPU monitoring work on
+        native Linux only.
