CODE_OF_CONDUCT.md

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders 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, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be 
+reported to the community leaders responsible for enforcement at 
+[corona-warn-app.opensource@sap.com](mailto:corona-warn-app.opensource@sap.com).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

CONTRIBUTING.md

+# Contributing
+
+## Code of Conduct
+
+All members of the project community must abide by the [Contributor Covenant, version 2.0](CODE_OF_CONDUCT.md).
+Only by respecting each other we can develop a productive, collaborative community.
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting [corona-warn-app.opensource@sap.com](mailto:corona-warn-app.opensource@sap.com) and/or a project maintainer. 
+
+We appreciate your courtesy of avoiding political questions here. Issues which are not related to the project itself will be closed by our community managers. 
+
+## Engaging in Our Project
+
+We use GitHub to manage reviews of pull requests.
+
+* If you are a new contributor, see: [Steps to Contribute](#steps-to-contribute)
+
+* If you have a trivial fix or improvement, go ahead and create a pull request, addressing (with `@...`) a suitable maintainer of this repository (see [CODEOWNERS](CODEOWNERS) of the repository you want to contribute to) in the description of the pull request.
+
+* If you plan to do something more involved, please reach out to us and send an [email](mailto:corona-warn-app.opensource@sap.com). This will avoid unnecessary work and surely give you and us a good deal of inspiration.
+
+* Relevant coding style guidelines are available in the respective sub-repositories as they are programming language-dependent.
+
+## Steps to Contribute
+
+Should you wish to work on an issue, please claim it first by commenting on the GitHub issue that you want to work on. This is to prevent duplicated efforts from other contributors on the same issue.
+
+If you have questions about one of the issues, please comment on them, and one of the maintainers will clarify.
+
+We kindly ask you to follow the [Pull Request Checklist](#Pull-Request-Checklist) to ensure reviews can happen accordingly.
+
+## Contributing Code
+
+You are welcome to contribute code in order to fix a bug or to implement a new feature.
+
+The following rule governs code contributions:
+
+* Contributions must be licensed under the [Apache 2.0 License](LICENSE)
+
+## Contributing Documentation
+
+You are welcome to contribute documentation to the project.
+
+The following rule governs documentation contributions:
+
+* Contributions must be licensed under the same license as code, the [Apache 2.0 License](LICENSE)
+
+## Pull Request Checklist
+
+* Branch from the master branch and, if needed, rebase to the current master branch before submitting your pull request. If it doesn't merge cleanly with master, you may be asked to rebase your changes.
+
+* Commits should be as small as possible while ensuring that each commit is correct independently (i.e., each commit should compile and pass tests).
+
+* Test your changes as thoroughly as possible before you commit them. Preferably, automate your test by unit/integration tests. If tested manually, provide information about the test scope in the PR description (e.g. “Test passed: Upgrade version from 0.42 to 0.42.23.”).
+
+* Create _Work In Progress [WIP]_ pull requests only if you need clarification or an explicit review before you can continue your work item.
+
+* If your patch is not getting reviewed or you need a specific person to review it, you can @-reply a reviewer asking for a review in the pull request or a comment, or you can ask for a review by contacting us via [email](mailto:corona-warn-app.opensource@sap.com).
+
+* Post review:
+  * If a review requires you to change your commit(s), please test the changes again.
+  * Amend the affected commit(s) and force push onto your branch.
+  * Set respective comments in your GitHub review to resolved.
+  * Create a general PR comment to notify the reviewers that your amendments are ready for another round of review.
+
+## Issues and Planning
+
+* We use GitHub issues to track bugs and enhancement requests.
+
+* Please provide as much context as possible when you open an issue. The information you provide must be comprehensive enough to reproduce that issue for the assignee. Therefore, contributors should use but aren't restricted to the issue template provided by the project maintainers.
+
+* When creating an issue, try using one of our issue templates which already contain some guidelines on which content is expected to process the issue most efficiently. If no template applies, you can of course also create an issue from scratch.
+
+* Please apply one or more applicable [labels](https://github.com/corona-warn-app/cwa-app-android/labels) to your issue so that all community members are able to cluster the issues better.
