+There are three “tiers”: passing, silver, and gold.
+
+### Passing
+We meet 100% of the “passing” criteria.
+
+### Silver
+We meet 95% of the “silver” criteria. The gaps are as follows:
+  - we do not have a DCO or a CLA process for contributions.
+  - because we only have one maintainer, the project has no way to continue if that maintainer stops being active.
+  - we do not currently document “what the user can and cannot expect in terms of security” for our project. This is planned to be completed in 2023.
+
+### Gold
+We meet 65% of the “gold” criteria. The gaps are as follows:
+  - we do not yet have the “silver” badge; see all the gaps above.
+  - We do not include a copyright or license statement in each source file. Efforts are underway to change this archaic practice into a suggestion instead of a hard requirement.

+# `nvm` Threat Model
+
+## Introduction
+
+Threat model analysis assists organizations to proactively identify potential security threats and vulnerabilities, enabling them to develop effective strategies to mitigate these risks before they are exploited by attackers.
+Furthermore, this often helps to improve the overall security and resilience of a system or application.
+
+The aim of this section is to facilitate the identification of potential security threats and vulnerabilities that may be exploited by adversaries, along with possible outcomes and appropriate mitigations.
+
+## Relevant assets and threat actors
+
+The following assets are considered important for the `nvm` project:
+  - `nvm` source code and project documentation
+  - Underlying `nvm` dependencies
+  - `nvm` development infrastructure
+  - `nvm` installed devices including servers
+
+The following threat actors are considered relevant to the `nvm` application:
+  - External malicious attackers
+  - Internal malicious attackers
+  - Services
+  - Malicious insider actors
+  - Third-party libraries
+
+## Attack surface for external/internal attackers and services
+
+In threat modeling, an attack surface refers to any possible point of entry that an attacker might use to exploit a system or application.
+This includes all the paths and interfaces that an attacker may use to access, manipulate or extract sensitive data from a system.
+By understanding the attack surface, organizations are typically able to identify potential attack vectors and implement appropriate countermeasures to mitigate risks.
+
+In the following diagrams, _External Malicious Attacker_ applies to threat actors who do not yet have direct access to the `nvm` application and the underlying operating system, while the _Internal Malicious Attacker_ applies to an attacker with access to the device (computer, server), potentially after successfully exploiting a threat from the _External Malicious Attacker_ scenario.
+**Please note that some of the external threats may be also exploitable from internal threats and vice versa.**
+
+<img src="./external-threat-actor.png" alt="Fig.: Possible attacks from internal and external threat actors and services" />
+Fig.: Possible attacks from internal and external threat actors and services
+
+## Identified threats
+
+The identified threats against the `nvm` application are as follows:
+
+### Threat ID 1: `nvm` commands
+
+Overview: The `nvm` commands and subcommands take user input for handling and executing appropriate functions from the project directory (or any parent directory).
+When user-controlled inputs are not adequately validated and later passed to the `nvm` functions as a part of a command, an attacker might be able to execute operating system commands triggered by any parsing functionality.
+
+Possible Outcome: Attacks against `nvm` commands could lead to unauthorized access to user data or unauthorized access to the device (i.e. laptop or server, depending on where `nvm` is installed), resulting in loss of user private data stored on the device, among other possibilities.
+
+Recommendation: Input validation should be implemented to prevent attackers from requesting operating system commands.
+Similarly, secure coding practices ought to be in place to minimize the risk of buffer overflow vulnerabilities.
+
+### Threat ID 2: URI scheme
+
+Overview: `nvm` commands heavily use the [Secure HyperText Transfer](https://datatracker.ietf.org/doc/html/rfc2660) protocol for `nvm` related actions.
+Missing [scheme](https://datatracker.ietf.org/doc/html/rfc3986#section-3.1) validation for any `nvm` command might result in file retrieval, enumeration, file overwrite, or [path traversal](https://owasp.org/www-project-web-security-testing-guide/latest/4-Web_Application_Security_Testing/05-Authorization_Testing/01-Testing_Directory_Traversal_File_Include) attacks.
+An example of this could be path validation for [`nvm_download`](https://github.com/nvm-sh/nvm/blob/ef7fc2f2c06ad75fe7fbabf28d427561ae7b007d/nvm.sh#L118), among many other possibilities.
+
+Possible Outcome: Security misconfiguration flaws for URI scheme may lead to unauthorized access to user data, as well as data integrity compromises.
+
+Recommendation: Adequate input validation should be implemented to prevent attackers from enumerating, retrieving and writing to application files and paths.
+
+### Threat ID 3: Communication channel
+
+Overview: The `nvm` commands and its subcommands use network protocol to communicate with external services.
+Insecure communication may allow malicious attackers to perform [_Man-in-the-Middle_](https://owasp.org/www-community/attacks/Manipulator-in-the-middle_attack) attacks in order to manipulate the data sent during the users’ active connection.
+
+Possible Outcome: Usage of plaintext communication protocols, like HTTP could lead to data sniffing and modification through insecure communications channels.
+
+Recommendation: Mitigation countermeasures such as data encryption should be in place to prevent data manipulation via insecure communication channels.
+
+### Threat ID 4: Environment variables
+
+Overview: Each `nvm` installation defines its environment variables, which should be secured from internal malicious attackers, preventing access control attack vectors.
+Missing stringent restrictions on setting variables, might allow attackers to prepare various targeted attacks against other local users, who use `nvm` in their user space.
+For example, [_Privilege Escalation_](https://owasp.org/Top10/A01_2021-Broken_Access_Control/), [_Command Injection_](https://cwe.mitre.org/data/definitions/77.html), as well as many other parser-related attacks.
+
+Possible Outcome: Attacks against environment variables could lead to unauthorized access to the user space, resulting in the loss of user private data and disruptions in service availability.
+
+Recommendation: Adequate hardening of configuration file permissions should be in place for all relevant configuration files, as this provides protection against attackers able to manipulate variables and inject malicious code.
+
+## Attack surface for malicious insider actors and third-party libraries
+
+The following diagram summarizes the main possible threats against the `nvm` project from malicious insider actors and third-party libraries:
+
+<img src="./insider-threat-actor-and-libs.png" alt="Fig.: Possible attacks from insider threat actors and third-party libraries" />
+Fig.: Possible attacks from insider threat actors and third-party libraries
+
+The identified threats against the `nvm` project are as follows:
+
+### Threat ID 1: Insider threat actor
+
+**Overview**: An insider threat actor, such as an `nvm` project contributor or employee with access to the code base, might abuse their role in the organization to modify the `nvm` application source code.
+For example, intentionally adding malicious code snippets, clearing logs after being written and/or modifying specific sections of the documentation.
+
+**Possible Outcome**: Reputation damage, financial losses.
+
+**Recommendation**: Secure coding practices, code reviews, automated code scanning and separation of duties (i.e. requiring at least two developers to approve any code change) are potentially useful security controls to identify and mitigate vulnerabilities that may be introduced by an insider threat actor.
+
+### Threat ID 2: Third-party libraries
+
+**Overview**: Please note that while `nvm` does not currently make use of any third-party libraries, this might become an attack vector if that changes in the future.
+Third-party libraries may introduce potential risks related to maintaining security requirements by third-party vendors.
+As a result, third-party libraries used by the `nvm` project, might contain vulnerabilities, such as [_Buffer Overflows_](https://owasp.org/www-community/vulnerabilities/Buffer_Overflow), [_Format String Vulnerabilities_](https://owasp.org/www-community/attacks/Format_string_attack), as well as many other types of weaknesses that, in a worst-case scenario may lead to _Remote Code Execution_ (_RCE_).
+Additionally, the maintainer of a third-party dependency might introduce a vulnerability on purpose, or be compromised by an attacker that subsequently introduces vulnerable code.
+
+**Possible Outcome**: Code vulnerabilities may lead to unauthorized access to user data, loss of user private data, service disruptions and reputation damage.
+
+**Recommendation**: Third-party libraries should be kept up-to-date, applying patches to address publicly known vulnerabilities in a timely fashion.
+Monitoring and logging capabilities should also be in place to detect and respond to potential attacks.
+SLSA compliance may also be considered for further supply chain security hardening.

+# Code of Conduct
+
+`nvm`, as a member project of the OpenJS Foundation, uses [Contributor Covenant v2.1](https://www.contributor-covenant.org/version/2/1/code_of_conduct/) as their code of conduct. The full text is included [below](#contributor-covenant-code-of-conduct) in English, and translations are available from the Contributor Covenant organisation:
+
+- [contributor-covenant.org/translations](https://www.contributor-covenant.org/translations)
+- [github.com/ContributorCovenant](https://github.com/ContributorCovenant/contributor_covenant/tree/release/content/version/2/1)
+
+Refer to the sections on reporting and escalation in this document for the specific emails that can be used to report and escalate issues.
+
+## Reporting
+
+### Project Spaces
+
+For reporting issues in spaces related to `nvm` please use the email `ljharb@gmail.com`. `nvm` handles CoC issues related to the spaces that it maintains. Projects maintainers commit to:
+
+- maintain the confidentiality with regard to the reporter of an incident
+- to participate in the path for escalation as outlined in the section on Escalation when required.
+
+### Foundation Spaces
+
+For reporting issues in spaces managed by the OpenJS Foundation, for example, repositories within the OpenJS organization, use the email `report@lists.openjsf.org`.
+The Cross Project Council (CPC) is responsible for managing these reports and commits to:
+
+- maintain the confidentiality with regard to the reporter of an incident
+- to participate in the path for escalation as outlined in the section on Escalation when required.
+
+## Escalation
+
+The OpenJS Foundation maintains a Code of Conduct Panel (CoCP).
+This is a foundation-wide team established to manage escalation when a reporter believes that a report to a member project or the CPC has not been properly handled.
+In order to escalate to the CoCP send an email to `coc-escalation@lists.openjsf.org`.
+
+For more information, refer to the full [Code of Conduct governance document](https://github.com/openjs-foundation/cross-project-council/blob/HEAD/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, caste, color, 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 [@ljharb](ljharb@gmail.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.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 2.1, available at
+[https://www.contributor-covenant.org/version/2/1/code_of_conduct.html][v2.1].
+
+Community Impact Guidelines were inspired by

-Thanks for contributing to `nvm`!
+# Contributing
+
+:+1::tada: First off, thanks for taking the time to contribute to `nvm`! :tada::+1:
 
 We love pull requests and issues, they're our favorite.
 
+The following is a set of guidelines for contributing to `nvm` managed by [@LJHarb](https://github.com/ljharb), which is hosted on GitHub. These are mostly guidelines, not rules. Use your best judgment, and feel free to propose changes to this document in a pull request.
+
 However, before submitting, please review the following:
 
-For bug reports:
+# How Can I Contribute?
 
-  - Please make sure the bug is reproducible, and give us the steps to reproduce it, so that we can dig into the problem.
-  - Please give us as much detail as possible about your environment, so we can more easily confirm the problem.
+There are lots of ways to get involved. Here are some suggestions of things we'd love some help with.
 
-For pull requests:
+## Resolving existing issues
+
+You can consider helping out with issues already requiring attention - look for a "help wanted" label.
+
+### How Do I Submit a (Good) Bug Report? :bug:
+
+Explain the problem and include additional details to help maintainers reproduce the problem:
+
+* **Use a clear and descriptive title** for the issue to identify the problem.
+
+* **Describe the exact steps which reproduce the problem** in as many details as possible. For example, start by explaining which command exactly you used in the terminal. When listing steps, **don't just say what you did, but explain how you did it**. For example, if you moved the cursor to the end of a line, explain if you used the mouse, or a keyboard shortcut or a command, and if so which one?
+* **Provide specific examples to demonstrate the steps**. Include links to files or Github projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets in the issue, use [Markdown code blocks](https://help.github.com/articles/markdown-basics/#multiple-lines).
+* **Describe the behavior you observed after following the steps** and point out what exactly is the problem with that behavior.
+* **Explain which behavior you expected to see instead and why.**
+* **Provide as much context as possible** in order to help others verify and ultimately fix the issue. This includes giving us as much details as possible about your environment, so we can more easily confirm the problem.
+
+## Documentation
+
+We are happy to welcome contributions from anyone willing to improve documentation by adding missing information or making it more consistent and coherent.
+
+# Dev Environment
+
+Please refer to the [README](README.md) for complete instructions how to install, update, as well as troubleshoot `nvm` in your environment depending on your Operating System.

+# `nvm` Charter
+
+nvm is a version manager for Node.js, designed to be installed per-user, and invoked per-shell. nvm works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and Windows WSL.
+
+## Section 0: Guiding Principles
+
+The `nvm` project is part of the [OpenJS Foundation][openjs foundation], which operates transparently, openly, collaboratively, and ethically. Project proposals, timelines, and status must not merely be open, but also easily visible to outsiders.
+
+## Section 1: Scope
+
+`nvm` is a node version manager, focused on making it easy to install and manage multiple Node.js versions. Any features related to managing the installation and removal of Node.js on any node-supported platform are potentially in scope.
+
+## Section 2: Relationship with OpenJS Foundation CPC.
+
+Technical leadership for the projects within the [OpenJS Foundation][openjs foundation] is delegated to the projects through their project charters by the [OpenJS Foundation Cross-Project Council](https://openjsf.org/about/governance/) (CPC). In the case of the `nvm` project, it is delegated to the [`nvm` Maintainers](README.md#maintainers) (the “Maintainers”). The OpenJS Foundation's business leadership is the Board of Directors (the “Board”).
+
+This `nvm` Charter reflects a carefully constructed balanced role for the Maintainers and the CPC in the governance of the OpenJS Foundation. The charter amendment process is for the Maintainers to propose changes using simple majority of the full Maintainers, the proposed changes being subject to review and approval by the CPC. The CPC may additionally make amendments to the project charter at any time, though the CPC will not interfere with day-to-day discussions, votes or meetings of the Maintainers.

+### 2.1 Other Formal Project Relationships
+
+Section Intentionally Left Blank
+
+## Section 3: `nvm`'s Maintainers Governing Body
+
+`nvm` is governed by its [maintainers](README.md#maintainers).
+
+## Section 4: Roles & Responsibilities
+
+The roles and responsibilities of `nvm`'s Maintainers are described in [GOVERNANCE.md](./GOVERNANCE.md).
+
+### Section 4.1 Project Operations & Management
+

+### Section 4.3: Other Project Roles
+
+Section Intentionally Left Blank
+
+## Section 5: Definitions
+
+  - *Contributors*: contribute code or other artifacts, but do not have the right to commit to the codebase. Contributors work with the project’s maintainers to have code committed to the code base. A Contributor may be promoted to a Maintainer by the Maintainers. Contributors should rarely be encumbered by the Maintainers and never by the CPC or OpenJS Foundation Board.
+
+  - *Maintainers*: Contributors with any kind of decision-making authority in the project.
