# NimbusKV Contributor License Agreement

Version 1.0

Thank you for contributing to NimbusKV. This agreement lets the project
accept your contribution while keeping clear ownership of the codebase,
so NimbusKV can stay free under the Apache License 2.0 and can also be
offered under other terms (for example, commercial licenses) in the
future.

**You keep the copyright in your contribution.** You are giving the
project a broad license to use it, not transferring ownership.

## 1. Definitions

- **"Maintainer"** means Hemanshu Vaidya, the owner of the NimbusKV
  project, and any successor or assignee of the NimbusKV project.
- **"You"** means the individual, or the legal entity on whose behalf
  the individual signs, who submits a Contribution.
- **"Contribution"** means any code, documentation, or other material
  that You submit to the NimbusKV project (for example, through a pull
  request, patch, or issue) and intend to be included in it.

## 2. Copyright license

You grant the Maintainer, and anyone who receives software distributed
by the Maintainer, a perpetual, worldwide, non-exclusive, no-charge,
royalty-free, irrevocable license to reproduce, prepare derivative works
of, publicly display, publicly perform, sublicense, and distribute Your
Contributions and derivative works of them, **under any license terms,
including proprietary or commercial terms.**

## 3. Patent license

You grant the Maintainer, and anyone who receives software distributed
by the Maintainer, a perpetual, worldwide, non-exclusive, no-charge,
royalty-free, irrevocable patent license to make, use, sell, offer for
sale, import, and otherwise transfer Your Contributions, for any patent
claims You can license that are necessarily infringed by Your
Contribution alone or in combination with NimbusKV.

## 4. Your promises

You confirm that:

1. You have the legal right to grant the licenses above. If your
   employer or anyone else has rights in the Contribution (for example,
   under an employment contract), you have their permission, or they
   have signed this agreement.
2. The Contribution is your original work, or you have clearly
   identified any part of it that is not, along with its source and
   license.
3. To your knowledge, the Contribution does not violate anyone else's
   rights.

## 5. No obligation

The Maintainer is not required to use or include Your Contribution.
Contributions are provided "AS IS", without warranties of any kind,
except as stated in section 4.

## 6. How to sign

Comment on your pull request with this exact sentence:

Signing once covers all your future contributions, unless this
agreement is updated to a new version.

*This agreement has not yet been reviewed by a lawyer. The Maintainer
intends to have it reviewed; the version in this repository at the time
you sign is the one that applies to you.*
