 This can be also used to access the computation results directly from the file system.
 
+## Using GPU Acceleration for SIFT processing inside NodeODM
+Since the ODM has support [of GPU acceleration](https://github.com/OpenDroneMap/ODM#gpu-acceleration) you can use another base image for GPU processing.
+
+To use this feature, you need to use the `opendronemap/nodeodm:gpu` docker image instead of `opendronemap/nodeodm` and you need to pass the `--gpus all` flag:
+```bash
+docker run -p 3000:3000 --gpus all opendronemap/nodeodm:gpu
+```
+
+The SIFT GPU implementation is OpenCL-based, so should work with most graphics card (not just NVIDIA).
+
+If you have an NVIDIA card, you can test that docker is recognizing the GPU by running:
+
+```
+docker run --rm --gpus all nvidia/cuda:10.0-base nvidia-smi
+```
+
+If you see an output that looks like this:
