+This document is a declaration of software quality for the `rcpputils` package, based on the guidelines in [REP-2004](https://www.ros.org/reps/rep-2004.html).
+
+# `rcpputils` Quality Declaration
+
+The package `rcpputils` claims to be in the **Quality Level 4** category.
+
+Below are the rationales, notes, and caveats for this claim, organized by each requirement listed in the [Package Requirements for Quality Level 4 in REP-2004](https://www.ros.org/reps/rep-2004.html).
+
+## Version Policy [1]
+
+### Version Scheme [1.i]
+
+`rcpputils` uses `semver` according to the recommendation for ROS Core packages in the [ROS 2 Developer Guide](https://index.ros.org/doc/ros2/Contributing/Developer-Guide/#versioning).
+
+### Version Stability [1.ii]
+
+`rcpputils` is not yet at a stable version, i.e. `>= 1.0.0`.
+
+### Public API Declaration [1.iii]
+
+All symbols in the installed headers are considered part of the public API.
+
+All installed headers are in the `include` directory of the package, headers in any other folders are not installed and considered private.
+
+### API Stability Within a Released ROS Distribution [1.iv]/[1.vi]
+
+`rcpputils` will not break public API within a released ROS distribution, i.e. no major releases once the ROS distribution is released.
+
+### ABI Stability Within a Released ROS Distribution [1.v]/[1.vi]
+
+`rcpputils` contains C code and therefore must be concerned with ABI stability, and will maintain ABI stability within a ROS distribution.
+
+## Change Control Process [2]
+
+`rcpputils` follows the recommended guidelines for ROS Core packages in the [ROS 2 Developer Guide](https://index.ros.org/doc/ros2/Contributing/Developer-Guide/#package-requirements).
+
+### Change Requests [2.i]
+
+This package requires that all changes occur through a pull request.
+
+### Contributor Origin [2.ii]
+
+ This package uses DCO as its confirmation of contributor origin policy. More information can be found in [CONTRIBUTING](CONTRIBUTING.md).
+
+### Peer Review Policy [2.iii]
+
+Following the recommended guidelines for ROS Core packages, all pull requests must have at least 1 peer review.
+
+### Continuous Integration [2.iv]
+
+All pull request must pass CI on all [tier 1 platforms](https://www.ros.org/reps/rep-2000.html#support-tiers)
+
+### Documentation Policy [2.v]
+
+All pull requests must resolve related documentation changes before merging.
+
+## Documentation [3]
+
+### Feature Documentation [3.i]
+
+`rcpputils` has a [feature list](docs/FEATURES.md) and each item in the list links to the corresponding feature documentation.
+There is documentation for all of the features, and new features require documentation before being added.
+
+### Public API Documentation [3.ii]
+
+`rcpputils` has embedded API documentation. It is not yet hosted publicly.
+
+### License [3.iii]
+
+The license for `rcpputils` is Apache 2.0, and a summary is in each source file, the type is declared in the `package.xml` manifest file, and a full copy of the license is in the [LICENSE](./LICENSE) file.
+
+There is an automated test which runs a linter that ensures each file has a license statement.
+
+Most recent test results can be found [here](http://build.ros2.org/view/Epr/job/Epr__rcpputils__ubuntu_bionic_amd64/lastBuild/testReport/rcpputils/)
+
+### Copyright Statements [3.iv]
+
+The copyright holders each provide a statement of copyright in each source code file in `rcpputils`.
+
+There is an automated test which runs a linter that ensures each file has at least one copyright statement.
+
+The results of the test can be found [here](http://build.ros2.org/view/Epr/job/Epr__rcpputils__ubuntu_bionic_amd64/lastBuild/testReport/rcpputils/copyright/).
+
+## Testing [4]
+
+### Feature Testing [4.i]
+
+Each feature in `rcpputils` has corresponding tests which simulate typical usage, and they are located in the `test` directory.
+New features are required to have tests before being added.
+
+### Public API Testing [4.ii]
+
+Each part of the public API have tests, and new additions or changes to the public API require tests before being added.
+The tests aim to cover both typical usage and corner cases, but are quantified by contributing to code coverage.
+
+### Coverage [4.iii]
+
+`rcpputils` does not currently track test coverage.
+
+### Performance [4.iv]
+
+`rcpputils` does not currently have performance tests.
+
+### Linters and Static Analysis [4.v]
+
+`rcpputils` uses and passes all the standard linters and static analysis tools for a C++ package as described in the [ROS 2 Developer Guide](https://index.ros.org/doc/ros2/Contributing/Developer-Guide/#linters).
+
+Results of the nightly linter tests can be found [here](http://build.ros2.org/view/Epr/job/Epr__rcpputils__ubuntu_bionic_amd64/lastBuild/testReport/rcpputils/).
+
+## Dependencies [5]
+
+### Direct Runtime ROS Dependencies [5.i]/[5.ii]
+
+`rcpputils` has the following runtime ROS dependencies:
+* `rcutils`
+
+It has several "buildtool" dependencies, which do not affect the resulting quality of the package, because they do not contribute to the public library API.
+It also has several test dependencies, which do not affect the resulting quality of the package, because they are only used to build and run the test code.
+
+### Direct Runtime Non-ROS Dependencies [5.iii]
+
+`rcpputils` does not have any runtime non-ROS dependencies.
+
+## Platform Support [6]
+
+`rcpputils` supports all of the tier 1 platforms as described in [REP-2000](https://www.ros.org/reps/rep-2000.html#support-tiers), and tests each change against all of them.
+
+Currently nightly results can be seen here:
+* [linux-aarch64_release](https://ci.ros2.org/view/nightly/job/nightly_linux-aarch64_release/lastBuild/testReport/rcpputils/)
+* [linux_release](https://ci.ros2.org/view/nightly/job/nightly_linux_release/lastBuild/testReport/rcpputils/)
+* [mac_osx_release](https://ci.ros2.org/view/nightly/job/nightly_osx_release/lastBuild/testReport/rcpputils/)
+* [windows_release](https://ci.ros2.org/view/nightly/job/nightly_win_rel/lastBuild/testReport/rcpputils/)
