+# Docker Compose Watch Mode (2025 GA)
+
+Docker Compose Watch enables automatic hot reload during local development by synchronizing file changes instantly without manual container restarts.
+
+## Three Watch Actions
+
+### 1. sync - Hot Reload
+For frameworks with hot reload (React, Next.js, Node.js, Flask).
+Copies changed files directly into running container.
+
+### 2. rebuild - Compilation
+For compiled languages (Go, Rust, Java) or dependency changes.
+Rebuilds image and recreates container when files change.
+
+### 3. sync+restart - Config Changes
+For configuration files requiring restart.
+Syncs files and restarts container.
+
+## Usage
+
+```yaml
+services:
+  frontend:
+    build: ./frontend
+    develop:
+      watch:
+        - action: sync
+          path: ./frontend/src
+          target: /app/src
+          ignore: [node_modules/, .git/]
+        - action: rebuild
+          path: ./frontend/package.json
+```
+
+Start with: `docker compose up --watch`
+
+## Benefits
+- Better performance than bind mounts
+- No file permission issues
+- Intelligent syncing
+- Supports rebuild capability
+- Works on all platforms
