+# Adobe code of conduct
+
+## Our pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language.
+* Being respectful of differing viewpoints and experiences.
+* Gracefully accepting constructive criticism.
+* Focusing on what is best for the community.
+* Showing empathy towards other community members.
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances.
+* Trolling, insulting/derogatory comments, and personal or political attacks.
+* Public or private harassment.
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission.
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting.
+
+## Our responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at [email protected]. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the code of conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This code of conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [https://contributor-covenant.org/version/1/4][version].

+# Contributing
+
+We welcome contributions to this project!
+
+Before you start, we ask that you understand the following guidelines.
+
+## Code of conduct
+
+This project adheres to the Adobe [code of conduct](../CODE_OF_CONDUCT.md). By participating,
+you are expected to uphold this code. Please report unacceptable behavior to
+[[email protected]](mailto:[email protected]).
+
+## Have a question?
+
+Start by filing an issue. The existing committers on this project work to reach
+consensus around project direction and issue solutions within issue threads
+(when appropriate).
+
+### Current areas of work
+
+The Adobe CAI team has been using this crate as the foundation of Adobe's Content Authenticity Initiative-related products and services since late 2020. As we shift toward making this crate available for open usage, we're aware that there is quite a bit of work to do to create what we'd feel comfortable calling a 1.0 release. We've decided to err on the side of releasing earlier so that people can experiment with it and give us feedback.
+
+We expect to do work on a number of areas in the next few months while we remain in prerelease (0.x) versions. Some broad categories of work (and thus things you might expect to change) are:
+
+* We'll be reviewing and refining our APIs for ease of use and comprehension. We'd appreciate feedback on areas that you find confusing or unnecessarily difficult.
+* We'll also be reviewing our APIs for compliance with Rust community best practices. There are some areas (for example, use of public fields and how we take ownership vs references) where we know some work is required.
+* Our documentation is incomplete. We'll be working on refining the documentation.
+* Our testing infrastructure is incomplete. We'll be working on improving test coverage, memory efficiency, and performance benchmarks.
+
+### Desired feedback
+
+We welcome feedback on:
+
+* API design
+* Prioritization of upcoming development, especially:
+  * File format support
+  * Assertion support
+* Optimizations and performance concerns
+* Bugs or non-compliance with the C2PA spec
+* Additional platform support
+
+## Contributor license agreement
+
+All third-party contributions to this project must be accompanied by a signed contributor
+license agreement. This gives Adobe permission to redistribute your contributions
+as part of the project. [Sign our CLA](https://opensource.adobe.com/cla.html). You
+only need to submit an Adobe CLA one time, so if you have submitted one previously,
+you are good to go!
+
+## Code reviews
+
+All submissions should come in the form of pull requests and need to be reviewed
+by project committers. Read [GitHub's pull request documentation](https://help.github.com/articles/about-pull-requests/)
+for more information on sending pull requests.
+
+Code submissions will need to pass all automated tests in place at the time of submission.
+These include such things as Rust code format, Clippy/lint checks, and unit test coverage.
+
+We encourage you to raise an issue in GitHub before starting work on a major addition to the crate.
+This will give us an opportunity to discuss API design and avoid duplicate efforts.
+
+### Pull request titles
+
+The build process automatically adds a pull request (PR) to the [CHANGELOG](CHANGELOG.md) unless the title of the PR begins with `(IGNORE)`. Start PR titles with `(IGNORE)` for minor documentation updates and other trivial fixes that you want to specifically exclude from the CHANGELOG.
+
+Additionally, the build process takes specific actions if the title of a PR begins with certain special strings:
+- `(MINOR)`: Increments the minor version, per [semantic versioning](https://semver.org/) convention. **IMPORTANT:** This flag should be used for any API change that breaks compatibility with previous releases while this crate is in prerelease (version 0.x) status.
+- `(MAJOR)`: Increments the major version number, per [semantic versioning](https://semver.org/) convention.
+
+## From contributor to committer
+
+We love contributions from our community! If you'd like to go a step beyond contributor
+and become a committer with full write access and a say in the project, you must
+be invited to the project. The existing committers employ an internal nomination
+process that must reach lazy consensus (silence is approval) before invitations
+are issued. If you feel you are qualified and want to get more deeply involved,
+feel free to reach out to existing committers to have a conversation about that.
+
+## Security issues
+
+Security issues shouldn't be reported on this issue tracker. Instead,
+[file an issue to our security experts](https://helpx.adobe.com/security/alertus.html).

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
