+## CI/CD Pipeline
+
+The project includes a Gitea Actions workflow (`.gitea/workflows/ci.yaml`) for automated builds.
+
+### What CI Builds
+
+| Image | Architecture | Source |
+|-------|--------------|--------|
+| `paddle-ocr-cpu:amd64` | amd64 | PyPI paddlepaddle |
+| `paddle-ocr-cpu:arm64` | arm64 | Pre-built wheel from Gitea packages |
+| `paddle-ocr-gpu:amd64` | amd64 | PyPI paddlepaddle-gpu |
+| `paddle-ocr-gpu:arm64` | arm64 | Pre-built wheel from Gitea packages |
+
+### ARM64 Wheel Workflow
+
+Since PyPI wheels don't work on ARM64 (x86 SSE instructions), wheels must be built from source using sse2neon:
+
+1. Built manually on an ARM64 machine (one-time)
+2. Uploaded to Gitea generic packages
+3. Downloaded by CI when building ARM64 images
+
+#### Step 1: Build ARM64 Wheels (One-time, on ARM64 machine)
+
+```bash
+cd src/paddle_ocr
+
+# Build GPU wheel (requires NVIDIA GPU, takes 1-2 hours)
+sudo docker build -t paddle-builder:gpu-arm64 -f Dockerfile.build-paddle .
+sudo docker run --rm -v ./wheels:/wheels paddle-builder:gpu-arm64
+
+# Build CPU wheel (no GPU required, takes 1-2 hours)
+sudo docker build -t paddle-builder:cpu-arm64 -f Dockerfile.build-paddle-cpu .
+sudo docker run --rm -v ./wheels:/wheels paddle-builder:cpu-arm64
+
+# Verify wheels were created
+ls -la wheels/paddlepaddle*.whl
+# paddlepaddle_gpu-3.0.0-cp311-cp311-linux_aarch64.whl (GPU)
+# paddlepaddle-3.0.0-cp311-cp311-linux_aarch64.whl (CPU)
+```
+
+#### Step 2: Upload Wheels to Gitea Packages
+
+```bash
+export GITEA_TOKEN="your-token-here"
+
+# Upload GPU wheel
+curl -X PUT \
+  -H "Authorization: token $GITEA_TOKEN" \
+  --upload-file wheels/paddlepaddle_gpu-3.0.0-cp311-cp311-linux_aarch64.whl \
+  "https://seryus.ddns.net/api/packages/unir/generic/paddlepaddle-gpu-arm64/3.0.0/paddlepaddle_gpu-3.0.0-cp311-cp311-linux_aarch64.whl"
+
+# Upload CPU wheel
+curl -X PUT \
+  -H "Authorization: token $GITEA_TOKEN" \
+  --upload-file wheels/paddlepaddle-3.0.0-cp311-cp311-linux_aarch64.whl \
+  "https://seryus.ddns.net/api/packages/unir/generic/paddlepaddle-cpu-arm64/3.0.0/paddlepaddle-3.0.0-cp311-cp311-linux_aarch64.whl"
+```

+https://seryus.ddns.net/api/packages/unir/generic/paddlepaddle-cpu-arm64/3.0.0/paddlepaddle-3.0.0-cp311-cp311-linux_aarch64.whl
+```
+
+#### Step 3: CI Builds Images
+
+CI automatically:
+1. Downloads ARM64 wheels from Gitea packages (for arm64 builds only)
+2. Builds both CPU and GPU images for amd64 and arm64
+3. Pushes to registry with arch-specific tags
+
+### Required CI Secrets
+
+Configure these in Gitea repository settings:
+
+| Secret | Description |
+|--------|-------------|
+| `CI_READWRITE` | Gitea token with registry read/write access |
+
+### Manual Image Push
+
+```bash
+# Login to registry
+docker login seryus.ddns.net
+
+# Build and push CPU (multi-arch)
+docker buildx build -f Dockerfile.cpu \
+  --platform linux/amd64,linux/arm64 \
+  -t seryus.ddns.net/unir/paddle-ocr-api:cpu \
+  --push .
+
+# Build and push GPU (x86_64)
+docker build -f Dockerfile.gpu -t seryus.ddns.net/unir/paddle-ocr-api:gpu-amd64 .
+docker push seryus.ddns.net/unir/paddle-ocr-api:gpu-amd64
+
+# Build and push GPU (ARM64) - requires wheel in wheels/
+docker buildx build -f Dockerfile.gpu \
+  --platform linux/arm64 \
+  -t seryus.ddns.net/unir/paddle-ocr-api:gpu-arm64 \
+  --push .
+```
+
+### Updating the ARM64 Wheels
+
+When PaddlePaddle releases a new version:
+
+1. Update `PADDLE_VERSION` in `Dockerfile.build-paddle` and `Dockerfile.build-paddle-cpu`
+2. Rebuild both wheels on an ARM64 machine
+3. Upload to Gitea packages with new version
+4. Update `PADDLE_VERSION` in `.gitea/workflows/ci.yaml`
