+Build KloudBuster Docker Image
+-----------------------
+
+Two files are used to build the Docker image: *Dockerfile* and *.dockerignore*. The former provides all the build instructions while the latter provides the list of files/directories that should not be copied to the Docker image.
+
+In order to make the Docker image clean, remove all auto generated files from the root of your workspace first. Specify the image name and the tag, and feed them to docker build. Examples to build the image with name "$USER/koudbuster", tag "latest"::
+
+$ cd <koudbuster-ws-root>
+$ sudo docker build --tag=$USER/koudbuster:latest .
+
+The images should be available for use::
+
+$ sudo docker images
+REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
+xiyu3/kloudbuster   latest              0f17ae788c69        8 minutes ago       443.1 MB
+
+For exchanging purposes, the image could be saved to a tar archive. You can distribute the KloudBuster Docker image among your servers easily with this feature::
+
+$ sudo docker save -o <IMAGE_FILE> <IMAGE_ID>
