+
+# Background
+
+The [TSC Project Roles] defines the main roles for the Zephyr Project, including
+Maintainer, Collaborator, and Contributor.
+
+By default anyone that contributes code or documentation is a Contributor, but
+with the lowest [GitHub Permission Level] of Read. For example, Contributors
+with Read permission do not have the permission to add reviewers to a pull
+request.
+
+Use this template to nominate a GitHub user for the Contributor role with
+Triage permission level, which allows the user to add reviewers to a pull
+request and be added as a reviewer by other users.
+
+# Nomination
+
+## GitHub User
+
+Provide the following information about the GitHub user:
+
+1. Full Name
+1. GitHub username
+1. Organization (optional)
+
+## Supporting Documents
+
+Add links to 3-5 GitHub pull requests, in the Zephyr project, authored or
+reviewed by the GitHub user that demonstrate the user's dedication to the
+Zephyr project.
+

-Governing Board, the Zephyr Project Director (Linux Foundation), and the Zephyr
-Project Developer Advocate (Linux Foundation). You may refer to the [Governing
-Board](https://zephyrproject.org/governing-board/) and [Linux Foundation
-Staff](https://zephyrproject.org/staff/) web pages to identify who are the
-individuals currently holding these positions.
-All complaints will be reviewed and investigated promptly and fairly.
+reported by contacting the project team at conduct@zephyrproject.org.
+Reports will be received by Kate Stewart (Linux Foundation) and Amy Occhialino
+(Intel). 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.
 
-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.
+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.
