+## Usage
 
 ```docker build -f docker/ubuntu/Dockerfile --tag ethcore/parity:branch_or_tag_name .```
+
+## Usage - CentOS
+
+Builds a lightweight non-root Parity docker image:
+
+```
+git clone https://github.com/paritytech/parity-ethereum.git
+cd parity-ethereum
+./docker/centos/build.sh
+```
+
+Fully customised build:
+```
+PARITY_IMAGE_REPO=my-personal/parity \
+PARITY_BUILDER_IMAGE_TAG=build-latest \
+PARITY_RUNNER_IMAGE_TAG=centos-parity-experimental \
+./docker/centos/build.sh
+```
+
+
+Default values:
+```
+# The image name
+PARITY_IMAGE_REPO - parity/parity
+
+# The tag to be used for builder image, git commit sha will be appended
+PARITY_BUILDER_IMAGE_TAG - build
+
+# The tag to be used for runner image
+PARITY_RUNNER_IMAGE_TAG - latest
+```
+
+All default ports you might use will be exposed:
+```
+#           secret
+#      ipfs store     ui   rpc  ws   listener  discovery
+#      ↓    ↓         ↓    ↓    ↓    ↓         ↓
+EXPOSE 5001 8082 8083 8180 8545 8546 30303/tcp 30303/udp
