## CHANGELOG 

Authors are expected to include a changelog file with their pull requests. The changelog file
should be a new file created in the `changelogs/unreleased` folder. The file should follow the
naming convention of `pr-username` and the contents of the file should be your text for the
changelog.

    velero/changelogs/unreleased   <- folder
        000-username            <- file


## DCO Sign off

All authors to the project retain copyright to their work. However, to ensure
that they are only submitting work that they have rights to, we are requiring
everyone to acknowledge this by signing their work.

Any copyright notices in this repo should specify the authors as "the Velero contributors".

To sign your work, just add a line like this at the end of your commit message:

```
Signed-off-by: Joe Beda <joe@heptio.com>
```

This can easily be done with the `--signoff` option to `git commit`.

By doing this you state that you can certify the following (from https://developercertificate.org/):
