 Please note that deeper networks, or networks with more filters can improve accuracy. We train the model using a thin residual network architecture, since it provides good tradeoff in terms of accuracy, and the model is light-weight in terms of runtime (or flops) and memory (or number of parameters).
 
+#### Docker Quickstart
+This Docker quickstart guide can be used for evaluating the model quickly with minimal dependency installation.
+
+Install Docker Engine
+- [Windows Installation](https://docs.docker.com/v1.8/installation/windows/)
+- [Mac OSX Installation](https://docs.docker.com/v1.8/installation/mac/)
+- [Ubuntu Installation](https://docs.docker.com/v1.8/installation/ubuntulinux/)

+Build a caffe docker image (CPU) 
+```
+docker build -t caffe:cpu https://raw.githubusercontent.com/BVLC/caffe/master/docker/standalone/cpu/Dockerfile
+```
+
+Check the caffe installation
+```
+docker run caffe:cpu caffe --version
+caffe version 1.0.0-rc3
+```
+
+Run the docker image with a volume mapped to your `open_nsfw` repository. Your `test_image.jpg` should be located in this same directory.
+```
+cd open_nsfw
+docker run --volume=$(pwd):/workspace caffe:cpu \
+python ./classify_nsfw.py \
+--model_def nsfw_model/deploy.prototxt \
+--pretrained_model nsfw_model/resnet_50_1by2_nsfw.caffemodel \
+test_image.jpg
+```
+
+We will get the NSFW score returned:
+```
+NSFW score:   0.14057905972

 #### Running the model
 To run this model, please install [Caffe](https://github.com/BVLC/caffe) and its python extension and make sure pycaffe is available in your PYTHONPATH.
