+
+The Developer Certificate of Origin (DCO) is a lightweight way for contributors to certify that they wrote or otherwise have the right to submit the code they are contributing to the project.
+Here is the full text of the [DCO](http://developercertificate.org/):
+
+```
+Developer Certificate of Origin
+Version 1.1

+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all

+
+Contributors must sign-off that they adhere to these requirements by adding a `Signed-off-by` line to commit messages.
+
+```
+This is my commit message
+
+Signed-off-by: Random J Developer <[email protected]>
+```
+
+Git has a `-s` command line option to append this automatically to your commit message:
+
+```console
+$ git commit -s -m 'This is my commit message'
+```
+
+## How to Contribute
+
+1. Fork this repository, develop, and test your changes.
+1. Remember to sign off your commits as described above.
+1. Submit a pull request.
+
+***NOTE***: In order to make testing and merging of PRs easier, please submit changes to multiple charts in separate PRs.
+
+### Technical Requirements
+
+* Must pass linting and installing with the [chart-testing](https://github.com/helm/chart-testing) tool
+* Must follow [best practices](https://github.com/helm/helm/tree/master/docs/chart_best_practices) and [review guidelines](https://github.com/helm/charts/blob/master/REVIEW_GUIDELINES.md)
+
+### Documentation Requirements
+
+* A chart's `README.md` must include configuration options
+* A chart's `NOTES.txt` must include relevant post-installation information
+
+### Merge Approval and Release Process
+
+* Must pass DCO check
+* Must pass CI jobs for linting and installing changed charts
+* Any change to a chart requires a version bump following [semver](https://semver.org/) principles
+
+Once changes have been merged, the release job will automatically run to package and release changed charts.
