 # Webhook Timer
 
-A minimalistic timer for webhooks, designed specifically for N8N Webhooks.
-
-## Features
-- Minimalistic Go-based daemon
-- SQLite persistence for configuration
-- Web-UI for managing timers
-- Support for Fixed and Random intervals
-- WebSocket for live countdown updates
-- Ultra-lightweight Docker Image (~26MB)

-## Deployment
-
-### Docker Compose
-```yaml
-services:
-  timerhook:
-    image: ghcr.io/xhyperdevx/webhooktimer:latest
-    ports:
-      - "8080:8080"
-    volumes:
-      - ./data:/data
-    restart: unless-stopped
+A tiny 24/7 webhook scheduler with a minimal web UI.
+
+## What this rebuild includes
+
+- Extremely simple UI (single page, no frontend dependencies)
+- Fixed or random intervals
+- Sleep window (no executions during configured quiet time)
+- Per-entry enable/disable
+- Live countdown to next execution
+- Last execution status and timestamp
+- Per-entry execution log (last 10)
+- **Run now** button with immediate success/error feedback
+- Atomic JSON state persistence (new format, old DB files are intentionally not reused)
+
+## Why it is lightweight
+
+- Pure Go + standard library only
+- No JS framework, no CSS framework, no websocket dependency
+- Static binary in a `scratch` container image
+
+## Run locally
+
+```bash
+go run .
 ```
 
-## Local Development
-1. Install Go 1.23+
-2. `go run main.go`
-3. Access UI at `http://localhost:8080`
+Open: `http://localhost:8080`
+
+## Docker
+
+```bash
+docker compose up --build
+```
+
+### Environment variables
+
+- `PORT` (default `8080`)
+- `STATE_PATH` (default `/data/state.json`)
+- `TZ` (default `UTC`, used for sleep window calculations)
+
+## API (used by the UI)
+
+- `GET /api/entries`
+- `POST /api/entries`
+- `PUT /api/entries/{id}`
+- `DELETE /api/entries/{id}`
+- `POST /api/entries/{id}/toggle`
+- `POST /api/entries/{id}/execute`
+- `GET /api/entries/{id}/logs`
+
+## Notes
+
+- The new persistence format is JSON, not SQLite.
+- If an old database exists from previous versions, it is ignored by design.
