+# Tactility Book Player App
+
+The Book Player app for Tactility OS plays children's books stored on the SD card. Each book is organized in its own subfolder and contains a sequential layout of pages with both visual illustrations (images) and narration (audio).
+
+## SD Card Layout
+
+Books must be stored under `/sdcard/books/` on the device SD card with the following structure:
+
+```text
+/sdcard/books/
+  book_slug_1/
+    manifest.json
+    page001.png
+    page001.mp3
+    page002.png
+    page002.mp3
+    ...
+  book_slug_2/
+    manifest.json
+    page001.jpg
+    page001.wav
+    page002.jpg
+    page002.wav
+    ...
+```
+
+## Manifest Format
+
+Each book subfolder must contain a `manifest.json` file. Here is a sample format:
+
+```json
+{
+  "title": "Princess Grace and Poppy",
+  "author": "Reyna Family",
+  "id": "grace-poppy",
+  "format": "tactility-book-manifest-v1",
+  "display": {
+    "width": 320,
+    "height": 240
+  },
+  "audio": {
+    "encoding": "mp3",
+    "sample_rate_hz": 16000,
+    "channels": 1,
+    "bitrate_kbps": 24
+  },
+  "pages": [
+    {
+      "image": "page001.png",
+      "audio": "page001.mp3",
+      "caption": "Once upon a time, in a magnificent castle perched high on a hill above the sea, there lived five princesses..."
+    },
+    {
+      "image": "page002.png",
+      "audio": "page002.mp3",
+      "caption": "This is the story of Princess Grace..."
+    }
+  ]
+}
+```
+
+## Content Requirements
+
+- **Images**: PNG or JPG format. Recommended size is `320×240` pixels (or scaled to match standard aspect ratios).
+- **Audio**: Mono `MP3` or uncompressed standard `WAV` files. For ESP32-S3 systems, lower sampling rates (e.g. 16 kHz mono) are recommended for memory efficiency.
