+# Scrying Pool Documentation Pack
+
+✅ **Compendium is now built and ready!**
+
+## Structure
+
+- `scrying-pool-docs.db` - **Pre-built SQLite compendium database** (20KB)
+- `scrying-pool-guide.json` - Source JournalEntry content (English & French)
+- `assets/` - Screenshot images (5 JPG files)
+
+## What's Included
+
+The `scrying-pool-docs.db` file contains a **JournalEntry** with:
+- **2 pages**: English and French documentation
+- **Professional styling** with CSS
+- **5 screenshot references** (screenshot-main.jpg, screenshot-directors-board.jpg, etc.)
+
+## Current Setup
+
+The `module.json` defines the pack:
+```json
+{
+  "packs": [
+    {
+      "name": "scrying-pool-documentation",
+      "label": "Scrying Pool Documentation",
+      "path": "packs/scrying-pool-docs.db",
+      "system": "",
+      "type": "JournalEntry"
+    }
+  ]
+}
+```
+
+When the module is installed in FoundryVTT, the **"Scrying Pool Documentation"** compendium will appear under the **Modules** tab with the JournalEntry already populated.
+
+## Updating the Documentation
+
+To update the documentation content:
+
+### Option 1: Using the build script (Recommended)
+```bash
+# Edit the JSON source
+nano packs/scrying-pool-guide.json
+
+# Rebuild the database
+node scripts/build-compendium.cjs
+```
+
+### Option 2: Manual SQLite editing
+```bash
+sqlite3 packs/scrying-pool-docs.db
+```
+
+### Option 3: Using fvtt-cli (Alternative)
+```bash
+npm install -g @foundryvtt/fvtt-cli
+fvtt-cli pack create \
+  --input packs/scrying-pool-guide.json \
+  --output packs/scrying-pool-docs.db \
+  --type JournalEntry
+```
