+    <p>OpenAstroCC is an open-source native Linux control panel for the Astro A50
+    Gen 3 headset and base station. It replaces the Windows-only command center
+    for supported headset settings without requiring proprietary software.</p>
+    <p>Edit five-band equalizer profiles visually, choose or save EQ presets,
+    adjust microphone and sidetone options, inspect battery and charging
+    status, and back up or restore headset settings. Linux audio setup helps
+    configure separate Game and Voice streams.</p>
