+# OCR Application Deployment Guide
+
+This guide describes how to deploy the OCR application on a Linux host (e.g., Ubuntu/Debian).
+
+## Architecture
+- **Backend**: Containerized (FastAPI, Python 3.9).
+- **Database**: Containerized (PostgreSQL 15).
+- **Frontend**: Static files (Angular) served by Host Nginx.
+- **Reverse Proxy**: Host Nginx proxies requests to Frontend (Static) and Backend (API).
+
+## Prerequisites
+- **Deployment Host**: Docker & Docker Compose, Nginx.
+- **Build Machine**: Node.js & NPM (to run the package script).
+
+---
+
+## 1. Full Stack Deployment (Docker)
+
+The app connects to your **existing Postgres container** (`postgres-db`) in the `arbit-app_arbit-network`.
+
+1.  **Create the Database**:
+    Since we are using an existing postgres instance, we must manually create the `ocr_db`.
+    ```bash
+    # Run this on your host to create the DB inside the existing container
+    docker exec -it postgres-db psql -U postgres -c "CREATE DATABASE ocr_db;"
+    ```
+
+2.  **Navigate to the packaged directory**:
+    ```bash
+    cd ocr_build
+    ```
+
+3.  **Verify Environment**:
+    Ensure `.env.prod` exists and points to `DB_HOST=postgres-db`.
+    **Also configure your Email credentials** in `.env.prod` if you want the Mailbox feature to work (Gmail requires an App Password).
+    ```bash
+    cat .env.prod
+    ```
+
+4.  **Start App Containers**:
+    This will start `ocr_backend` and `ocr_frontend`.
+    ```bash
+    # Build and start in detached mode
+    docker-compose up -d --build
+    ```
+
+5.  **Verify Status**:
+    ```bash
+    docker-compose ps
+    ```
+    You should see `ocr_backend` and `ocr_frontend` running.
+
+---
+
+## 2. Nginx Configuration (Host Reverse Proxy)
+
+Since the Frontend is now running in a container on port 8080 (serving `/ocrf/`), we configure the Host Nginx to proxy traffic to it.
+
+1.  **Create Config File**:
+    Copy the provided config to `/etc/nginx/sites-available/ocr`.
+    ```bash
+    sudo cp nginx_host.conf /etc/nginx/sites-available/ocr
+    ```
+
+2.  **Enable Site**:
+    ```bash
+    sudo ln -s /etc/nginx/sites-available/ocr /etc/nginx/sites-enabled/
+    ```
+
+3.  **Test & Reload**:
+    ```bash
+    sudo nginx -t
+    sudo systemctl reload nginx
+    ```
+
+---
+
+## 3. Verification
+
+- **Url**: `http://app.technobeesolutions.in/ocrf/` (Proxies to Frontend Container)
+- **API**: `http://app.technobeesolutions.in/ocrb/` (Proxies to Backend Container)
+
+---
+
+## 4. Troubleshooting
+
+- **Logs**:
+    ```bash
+    docker-compose logs -f backend
+    ```
+- **Database**:
+    Connect via the existing container:
+    ```bash
+    docker exec -it postgres-db psql -U postgres -d ocr_db
+    ```

-## Processing Pipeline
-
-When a document is uploaded, the following Celery task pipeline executes asynchronously:
-
-1. **File Type Detection** — Determine if the document is a native PDF or scanned image.
-2. **Page Extraction** — Convert PDF pages to images (for scanned docs) or parse directly (for native PDFs).
-3. **OCR** — Run PaddleOCR on scanned pages to extract text blocks with coordinates, confidence, and bounding boxes.
-4. **Native PDF Parsing** — Use PyMuPDF to extract text, fonts, images, and tables from native PDFs.
-5. **Layout Analysis** — Detect headers, footers, watermarks, tables, and image regions using OpenCV heuristics.
-6. **Template Generation** — Build a reusable template definition from the detected layout, stored in PostgreSQL.
-7. **Fingerprint Generation** — Compute a structural fingerprint (SHA-256) for future matching.
-8. **Status Update** — Mark the document as `completed` (or `failed` with error details).
