 Modern OCR web application powered by DeepSeek-OCR with a stunning React frontend and FastAPI backend.
 
-> **Note**: This was a quickly vibe-coded project to test out DeepSeek-OCR! It basically works quite nice on an RTX 5090. The "Find" mode grounding boxes aren't quite working yet - probably my fault in not interpreting the dimensions correctly, but the core OCR functionality is pretty nice so far.
+> **Recent Updates (v2.1.1)**
+> - ✅ Fixed image removal button - now properly clears and allows re-upload
+> - ✅ Fixed multiple bounding boxes parsing - handles `[[x1,y1,x2,y2], [x1,y1,x2,y2]]` format
+> - ✅ Simplified to 4 core working modes for better stability
+> - ✅ Fixed bounding box coordinate scaling (normalized 0-999 → actual pixels)
+> - ✅ Fixed HTML rendering (model outputs HTML, not Markdown)
+> - ✅ Increased file upload limit to 100MB (configurable)
+> - ✅ Added .env configuration support
 
 ## Quick Start
 
-```bash
-docker compose up --build
-```
+1. **Clone and configure:**
+   ```bash
+   git clone <repository-url>
+   cd deepseek_ocr_app
    
-Then open:
-- **Frontend**: http://localhost:3000
-- **Backend API**: http://localhost:8000
-- **API Docs**: http://localhost:8000/docs
+   # Copy and customize environment variables
+   cp .env.example .env
+   # Edit .env to configure ports, upload limits, etc.
+   ```
+
+2. **Start the application:**
+   ```bash
+   docker compose up --build
+   ```
+
+   The first run will download the model (~5-10GB), which may take some time.
+
+3. **Access the application:**
+   - **Frontend**: http://localhost:3000 (or your configured FRONTEND_PORT)
+   - **Backend API**: http://localhost:8000 (or your configured API_PORT)
+   - **API Docs**: http://localhost:8000/docs

 ## Requirements
 
-- Docker & Docker Compose
-- NVIDIA GPU with CUDA support (tested on RTX 5090)
-- nvidia-docker runtime
-- ~8-12GB VRAM for model
+### Hardware
+- NVIDIA GPU with CUDA support
+  - Recommended: RTX 3090, RTX 4090, RTX 5090, or newer
+  - Minimum: 8-12GB VRAM for the model
+  - More VRAM allows for larger batch sizes and higher resolution images
 
-## Known Issues
+### Software
+- **Docker & Docker Compose** (latest version recommended)
 
-- 📦 **Find mode grounding boxes**: Not rendering correctly - likely dimension scaling issue in the canvas overlay logic. Boxes are detected and returned by the backend, but the frontend visualization needs work.
+- **NVIDIA Driver** - Installing NVIDIA Drivers on Ubuntu (Blackwell/RTX 5090)
+
+  **Note**: Getting NVIDIA drivers working on Blackwell GPUs can be a pain! Here's what worked:
+
+  The key requirements for RTX 5090 on Ubuntu 24.04:
+  - Use the open-source driver (nvidia-driver-570-open or newer, like nvidia-driver-580-open)
+  - Upgrade to kernel 6.11+ (6.14+ recommended for best stability)
+  - Enable Resize Bar in BIOS/UEFI (critical!)
+
+  **Step-by-Step Instructions:**
+
+  1. Install NVIDIA Open Driver (580 or newer)
+     ```bash
+     sudo add-apt-repository ppa:graphics-drivers/ppa
+     sudo apt update
+     sudo apt remove --purge nvidia*
+     sudo nvidia-installer --uninstall  # If you have it
+     sudo apt autoremove
+     sudo apt install nvidia-driver-580-open
+     ```
+
+  2. Upgrade Linux Kernel to 6.11+ (for Ubuntu 24.04 LTS)
+     ```bash
+     sudo apt install --install-recommends linux-generic-hwe-24.04 linux-headers-generic-hwe-24.04
+     sudo update-initramfs -u
+     sudo apt autoremove
+     ```
+
+  3. Reboot
+     ```bash
+     sudo reboot
+     ```
+
+  4. Enable Resize Bar in UEFI/BIOS
+     - Restart and enter UEFI (usually F2, Del, or F12 during boot)
+     - Find and enable "Resize Bar" or "Smart Access Memory"
+     - This will also enable "Above 4G Decoding" and disable "CSM" (Compatibility Support Module)—that's expected!
+     - Save and exit
+
+  5. Verify Installation
+     ```bash
+     nvidia-smi
+     ```
+     You should see your RTX 5090 listed!
+
+  💡 **Why open drivers?** I dunno, but the open drivers have better support for Blackwell GPUs. Without Resize Bar enabled, you'll get a black screen even with correct drivers!

+
+- **NVIDIA Container Toolkit** (required for GPU access in Docker)
+  - Installation guide: https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html
+
+### System Requirements
+- ~20GB free disk space (for model weights and Docker images)
+- 16GB+ system RAM recommended
+- Fast internet connection for initial model download (~5-10GB)
+
+## Known Issues & Fixes
+
+### ✅ FIXED: Image removal and re-upload (v2.1.1)
+- **Issue**: Couldn't remove uploaded image and upload a new one
+- **Fix**: Added prominent "Remove" button that clears image state and allows fresh upload
+
+### ✅ FIXED: Multiple bounding boxes (v2.1.1)
+- **Issue**: Only single bounding box worked, multiple boxes like `[[x1,y1,x2,y2], [x1,y1,x2,y2]]` failed
+- **Fix**: Updated parser to handle both single and array of coordinate arrays using `ast.literal_eval`
+
+### ✅ FIXED: Grounding box coordinate scaling (v2.1)
+- **Issue**: Bounding boxes weren't displaying correctly
+- **Cause**: Model outputs coordinates normalized to 0-999, not actual pixel dimensions
+- **Fix**: Backend now properly scales coordinates using the formula: `actual_coord = (normalized_coord / 999) * image_dimension`
+
+### ✅ FIXED: HTML vs Markdown rendering (v2.1)
+- **Issue**: Output was being rendered as Markdown when model outputs HTML
+- **Cause**: Model is trained to output HTML (especially for tables)
+- **Fix**: Frontend now detects and renders HTML properly using `dangerouslySetInnerHTML`
+
+### ✅ FIXED: Limited upload size (v2.1)
+- **Issue**: Large images couldn't be uploaded
+- **Fix**: Increased nginx `client_max_body_size` to 100MB (configurable via .env)
+
+### ⚠️ Simplified Mode Selection (v2.1.1)
+- **Change**: Reduced from 12 modes to 4 core working modes
+- **Reason**: Advanced modes (tables, layout, PII, multilingual) need additional testing
+- **Working modes**: Plain OCR, Describe, Find, Freeform
+- **Future**: Additional modes will be re-enabled after thorough testing
+
+## How the Model Works
+
+### Coordinate System
+The DeepSeek-OCR model uses a normalized coordinate system (0-999) for bounding boxes:
+- All coordinates are output in range [0, 999]
+- Backend scales: `pixel_coord = (model_coord / 999) * actual_dimension`
+- This ensures consistency across different image sizes
+
+### Dynamic Cropping
+For large images, the model uses dynamic cropping:
+- Images ≤640x640: Direct processing
+- Larger images: Split into tiles based on aspect ratio
+- Global view (BASE_SIZE) + Local views (IMAGE_SIZE tiles)
+- See `process/image_process.py` for implementation details
+
+### Output Format
+- Plain text modes: Return raw text
+- Table modes: Return HTML tables or CSV
+- JSON modes: Return structured JSON
+- Grounding modes: Return text with `<|ref|>label<|/ref|><|det|>[[coords]]<|/det|>` tags
 
 ## API Usage
 
 ### POST /api/ocr
 
 **Parameters:**
-- `image` (file, required)
-- `mode` (string): plain_ocr | describe | find_ref | freeform
-- `prompt` (string): Custom prompt for freeform mode
-- `grounding` (bool): Enable bounding boxes (auto-enabled for find_ref)
-- `find_term` (string): Term to locate in find_ref mode
-- `base_size` (int): Base processing size (default: 1024)
-- `image_size` (int): Image size (default: 640)
-- `crop_mode` (bool): Enable crop mode (default: true)
+- `image` (file, required) - Image file to process (up to 100MB)
+- `mode` (string) - OCR mode: `plain_ocr` | `describe` | `find_ref` | `freeform`
+- `prompt` (string) - Custom prompt for freeform mode
+- `grounding` (bool) - Enable bounding boxes (auto-enabled for find_ref)
+- `find_term` (string) - Term to locate in find_ref mode (supports multiple matches)
+- `base_size` (int) - Base processing size (default: 1024)
+- `image_size` (int) - Tile size for cropping (default: 640)
+- `crop_mode` (bool) - Enable dynamic cropping (default: true)
+- `include_caption` (bool) - Add image description (default: false)
 
 **Response:**
 ```json
 {
   "success": true,
-  "text": "Extracted text...",
+  "text": "Extracted text or HTML output...",
   "boxes": [{"label": "field", "box": [x1, y1, x2, y2]}],
   "image_dims": {"w": 1920, "h": 1080},
-  "metadata": {...}
+  "metadata": {
+    "mode": "layout_map",
+    "grounding": true,
+    "base_size": 1024,
+    "image_size": 640,
+    "crop_mode": true
+  }
 }
 ```
 
+**Note on Bounding Boxes:**
+- The model outputs coordinates normalized to 0-999
+- The backend automatically scales them to actual image dimensions
+- Coordinates are in [x1, y1, x2, y2] format (top-left, bottom-right)
+- **Supports multiple boxes**: When finding multiple instances, format is `[[x1,y1,x2,y2], [x1,y1,x2,y2], ...]`
+- Frontend automatically displays all boxes overlaid on the image with unique colors
