+# 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
+    ```

+-----------------------------------------------------------
+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to a
+new environment.
+
+"Author" refers to any designer, engineer, programmer, technical
+writer or other person who contributed to the Font Software.
+
+PERMISSION & CONDITIONS
+Permission is hereby granted, free of charge, to any person obtaining
+a copy of the Font Software, to use, study, copy, merge, embed, modify,
+redistribute, and sell modified and unmodified copies of the Font
+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,
+redistributed and/or sold with any software, provided that each copy
+contains the above copyright notice and this license. These can be
+included either as stand-alone text files, human-readable headers or
+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
+Modified Version, except to acknowledge the contribution(s) of the
+Copyright Holder(s) and the Author(s) or with their explicit written
+permission.
+
+5) The Font Software, modified or unmodified, in part or in whole,
+must be distributed entirely under this license, and must not be
+distributed under any other license. The requirement for fonts to
+remain under this license does not apply to any document created
+using the Font Software.
+
+TERMINATION
+This license becomes null and void if any of the above conditions are
+not met.
