+# Contributing to OOM
+
+Thanks for taking the time to contribute to OOM!
+Please see a few informations on how to dot it.
+
+## How to become a contributor and submit your own code
+
+### Environment setup
+
+In order to be able to check on your side before submitting, you'll need to
+install some binaries:
+
+* helm (satisfying the targeted version as seen in [setup guide](
+docs/oom_cloud_setup_guide.rst#software-requirements).
+* chartmuseum (in order to push dependency charts)
+* helm push (version 0.9.0 as of today)
+* make
+
+### Linting and testing
+
+OOM use helm linting in order to check that the templates rendering is correct
+with default values.
+
+first step is to start chartmuseum:
+
+```shell
+nohup chartmuseum --storage="local" --storage-local-rootdir="/tmp/chartstorage" \
+  --port 6464 &
+```
+
+then you add `local` repository to helm:
+
+```shell
+helm repo remove local && helm repo add local http://localhost:6464
+```
+
+As full rendering may be extremely long (~9h), you can only lint the common
+part and the component you're working on.
+Here's an example with AAI:
+
+```shell
+cd kubernetes
+make common && make aai
+```
+
+If you work on non default path, it's strongly advised to also render the
+template of your component / subcomponent to be sure it's as expected.
+
+Here's an example enabling service mesh on aai graphadmin:
+
+```shell
+cd aai/components/
+helm template --release-name onap --debug \
+  --set global.ingress.virtualhost.baseurl=toto \
+  --set global.ingress.enabled=true --set global.masterPassword="toto" \
+  --set global.serviceMesh.enabled=true --set global.serviceMesh.tls=true \
+  aai-graphadmin
+```
+
+All the output will be the rendered YAML if it's OK or you may see an error.
+Usually the errors comes from bad indentation or unknown value.
+
+### Contributing A Patch
+
+1. Fork the desired repo, develop and test your code changes.
+2. Sign the LFN CLA (<https://www.onap.org/cla>)
+3. Submit a pull request.
+4. Work with the reviewers on their suggestions.
+5. Ensure to rebase to the HEAD of your target branch and squash un-necessary
+   commits (
+   <https://blog.carbonfive.com/always-squash-and-rebase-your-git-commits/>)
+   before final merger of your contribution.

+# ONAP Operations Manager
+
+## Description
+
+The ONAP Operations Manager (OOM) is responsible for life-cycle management of
+the ONAP platform itself; components such as SO, SDNC, etc.
+
+It is not responsible for the management of services, VNFs or infrastructure
+instantiated by ONAP or used by ONAP to host such services or VNFs.
+
+OOM uses the open-source Kubernetes container management system as a means to
+manage the containers that compose ONAP where the containers are hosted either
+directly on bare-metal servers or on VMs hosted by a 3rd party management
+system.
+
+OOM ensures that ONAP is easily deployable and maintainable throughout its life
+cycle while using hardware resources efficiently.
+
+Full documentation is available in ONAP documentation in [operations and
+administration guides](
+https://docs.onap.org/en/latest/guides/onap-operator/index.html).
+
+## Contributing
+
+Please see [contributing](./CONTRIBUTING.md) file to learn on how to contribute
+
+## Issues
+
+All issues should be filled in [ONAP Jira](https://jira.onap.org).
