+## Building and using development images
+
+In some cases you want to build custom images to try out development code.
+The suggested way to do that is:
+
+```shell
+cd ~/cord/incubator/voltha
+REPOSITORY=voltha/ TAG=dev VOLTHA_BUILD=docker make build
+cd ~/cord/automation-tools/developer
+bash tag_and_push.sh dev 192.168.99.100:30500
+```
+
+_This set of commands will build the VOLTHA containers and push them to a local
+[docker registry](../prereqs/docker-registry.md) using a TAG called `dev`_
+
+> NOTE: Read more about the `tag_and_push` script [here](../prereqs/docker-registry.md)
+
+Once the images are pushed to a docker registry on the POD,
+you can use a values file like the following one:
+
+```yaml
+# voltha-values.yaml
+envoyForEtcdImage: 'voltha/voltha-envoy:dev'
+netconfImage: 'voltha/voltha-netconf:dev'
+ofagentImage: 'voltha/voltha-ofagent:dev'
+vcliImage: 'voltha/voltha-cli:dev'
+vcoreImage: 'voltha/voltha-voltha:dev'
+```
+
+and you can install VOLTHA using:
+
+```shell
+helm install -n voltha voltha -f voltha-values.yaml
+```
