+Building containers and VM images
+=================================
+
+NFVbench is delivered as Docker container which is built using the Dockerfile under the docker directory.
+This container includes the following parts:
+
+- TRex traffic generator
+- NFVbench orchestration
+- NFVbench test VM (qcow2)
+
+Versioning
+----------
+These 3 parts are versioned independently and the Dockerfile will determine the combination of versions that
+are packaged in the container for the version associated to the Dockerfile.
+
+The NFVbench version is controlled by the git tag that conforms to the semver version (e.g. "3.3.0").
+This tag controls the version of the Dockerfile used for building the container.
+
+The TRex version is controlled by the TREX_VER variable in Dockerfile (e.g. ENV TREX_VER "v2.56").
+TRex is installed in container from https://trex-tgn.cisco.com/trex/release/
+
+The Test VM version is controlled by the VM_IMAGE_VER variable in Dockerfile (e.g. ENV VM_IMAGE_VER "0.8").
+The VM is extracted from google storage (http://artifacts.opnfv.org)
+
+Updating the VM image
+---------------------
+
+When the VM image is changed, its version must be increased in order to distinguish from previous image versions.
+The version strings to change are located in 2 files:
+
+- docker/Dockerfile
+- nfvbench/nfvbenchvm/dib/build-image.sh
+
+Building and uploading the VM image
+-----------------------------------
+The VM image is built and uploaded to Google storage from the CI/CD whenever the
+commit text of a gerrit review contains the word "buildvm".
+
+For details on how this is done, refer to ./jjb/nfvbench/nfvbench.yaml in the opnfv releng repository.
+
+Building a new NFVbench container image
+---------------------------------------
+A new container image can be built and published to Dockerhub by CI/CD by applying a new semver tag to the
+nfvbench repository.
+
+
+Workflow summary
+----------------
+
+NFVbench code has changed:
+
+- commit with gerrit
+- apply a new semver tag to trigger the container image build/publication
+
+VM code has changed:
+
+- update VM version in the 2 locations
+- commit VM changes with gerrit and add "buildvm" in your commit message to trigger VM build and publish to google storage
+- apply a new semver tag to trigger the container image build/publication
+
+To increase the TRex version:
+
+- change the Trex version in Dockerfile
+- commit with gerrit
+- apply a new semver tag to trigger the container image build/publication
