+## 🎨 Themes
+
+GridTV ships with 4 built-in themes. To add your own, create a CSS file in `themes/` with these metadata comments at the top:
+
+```css
+/*
+ * @name  My Theme
+ * @emoji 🌙
+ */
+
+:root {
+  --bg: #0a0b0d;
+  --accent: #e8c842;
+  /* ... */
+}
+```
+
+Drop it in `themes/` — it appears in the theme selector automatically, no code changes needed.
+
+---
+
+## ▶️ Built-in Player
+
+Click on any **channel name** or **currently airing program** to open a PiP (picture-in-picture) player in the bottom-right corner.
+
+The player requires:
+- An **M3U URL** configured in setup (used to match channel names to stream URLs)
+- The **php-curl** extension installed on the server
+
+If your stream source (e.g. Tunarr) serves streams over HTTP while GridTV runs on HTTPS, `proxy.php` handles the relay transparently — no browser mixed-content errors.
+
+---
+
 ## ⚙️ Advanced configuration
 
 The following constants can be tweaked directly in `index.php`:
 
 ```js
 const PX_PER_MIN = 5;    // Horizontal zoom (pixels per minute)
-const HOURS_BEFORE = 1;   // Past hours visible in the grid
+const GRID_HOURS = 72;   // Total timeline duration (hours)
-const HOURS_AFTER  = 3;   // Future hours visible in the grid
 const ROW_H      = 80;   // Channel row height (px)
 ```
