+## Available tags
-runtime and conda-xxx image has installed miniconda3;
-cudaxxx images have installed all depedent libs using apt-get.
+* `devel`, with SINGA and the development packages installed on Ubuntu16.04 (no GPU)
+* `devel-cuda`, with SINGA, CUDA8.0, CUDNN5, and other development packages installed on Ubuntu16.04
-## Usage
+## Use the existing Docker images
- docker pull nusdbsystem/singa:<Tag>
- docker run -it nusdbsystem/singa:<Tag> /bin/bash
- nvidia-docker run -it nusdbsystem/singa:<Tag> /bin/bash
+Users can pull the Docker images from Dockerhub via
+
+ docker pull apache/singa:devel
+ # or
+ docker pull apache/singa:devel-cuda
+
+Run the docker container using
+
+ docker run -it apache/singa:devel /bin/bash
+ # or
+ docker run -it apache/singa:devel-cuda /bin/bash
+
+The latest SINGA code is under the `incubator-singa` folder.
+
+## Create new Docker images from Dockerfile
+
+New Docker images could be created by executing the following command within the
+Dockerfile folder, e.g., tool/docker/devel/
+
+ docker build -t singa:<TAG> -f Dockerfile
+
+The `<TAG>` is named as
+
+ devel|runtime[-CUDA|CPU][-CUDNN]
+
+* devel: development images with all dependent libs' header files installed and SINGA's source code; runtime: the minimal images which can run SINGA programs.
+* CUDA: cuda10.0, cuda9.0
+* CUDNN: cudnn7
+
+Here are some example tags:
+
+`devel-cuda9-cudnn7`, `devel-cuda9-cudnn7`, `devel-cuda10-cudnn7`, `devel-cpu`, `runtime-gpu` and `runtime-cpu`
+
+
+Please follow the existing Dockefiles under tool/docker/ to create other Dockefiles.
+The folder structure is like
+
+ level1: devel|runtime
+ level2: Dockerfile, OS
+ level3: Dockerfile, CUDA|MKLDNN
+
+
+For example, the path of the Dockerfile for `devel-cuda9-cudnn7` is `tool/docker/devel/ubuntu/cuda9/Dockerfile`.
