 # gen-oslo-openstack-helm
 Oslo Config Generator Hack to Generate Helm Configs
+
+## Usage
+
+From this directory run the following commands, adjusting for the OpenStack
+project and/or branch desired as necessary.
+
+``` bash
+docker build . -t gen-oslo-openstack-helm
+docker run -it --rm \
+  -e PROJECT="heat" \
+  -e PROJECT_BRANCH="stable/newton" \
+  -e PROJECT_REPO=https://git.openstack.org/openstack/heat.git \
+  gen-oslo-openstack-helm
+```
+
+This container will then drop you into a shell, at the project root with
+OpenStack-Helm formatted configuration files in the standard locations produced
+by genconfig for the project.
