+Docker instructions
+===================
+
+For using GPU capabilities of Faiss, you'll need to run "nvidia-docker"
+rather than "docker". Make sure that docker
+(https://docs.docker.com/engine/installation/) and nvidia-docker
+(https://github.com/NVIDIA/nvidia-docker) are installed on your system
+
+To build the "faiss" image, run
+
+  nvidia-docker build -t faiss .
+
+If you want to run the tests during the docker build, uncomment the
+last 3 "RUN" steps in the Dockerfile. But you might want to run the
+tests by yourself, so just run
+
+  nvidia-docker run -ti --name faiss faiss bash
+
+and run what you want. If you need a dataset (like sift1M), download it
+inside the created container, or better, mount a directory from the host
+
+  nvidia-docker run -ti --name faiss -v /my/host/data/folder/ann_dataset/sift/:/opt/faiss/sift1M faiss bash
+

 Hot to use Faiss in your own projects
