+# 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
+jtonye@ymail.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.

+# Security Policy
+
+## Proactive Security Measures
+
+To proactively detect and address security vulnerabilities, we utilize several robust tools and processes:
+
+- **Dependency Updates:** We use [Renovate](https://renovatebot.com) and [Dependabot](https://docs.github.com/en/code-security/dependabot/dependabot-security-updates/about-dependabot-security-updates) to keep our dependencies updated and promptly patch detected vulnerabilities through automated PRs.
+- **[GitHub's Security Features](https://github.com/features/security):** Our repository and dependencies are continuously monitored via GitHub's security features, which include:
+  - **Code Scanning:** Using GitHub's CodeQL, all pull requests are scanned to identify potential vulnerabilities in our source code.
+  - **Automated Alerts:** Dependabot identifies vulnerabilities based on the GitHub Advisory Database and opens PRs with patches, while automated [secret scanning](https://docs.github.com/en/enterprise-cloud@latest/code-security/secret-scanning/about-secret-scanning#about-secret-scanning-for-partner-patterns) provides alerts for detected secrets.
+- **[GitGuardian Security Checks](https://www.gitguardian.com/):** We employ GitGuardian to ensure security checks are performed on the codebase, enhancing the overall security of our project.
+- **Code Analysis and Security Scanning:** With the help of [Codacy Static Code Analysis](https://www.codacy.com/) and [Codacy Security Scan](https://security.codacy.com/), we conduct thorough analyses and scans of our code for potential security risks.
+
+## Reporting Security Vulnerabilities
+
+Despite our best efforts to deliver secure software, we acknowledge the invaluable role of the community in identifying security breaches.
+
+### Private Vulnerability Disclosures
+
+We request all suspected vulnerabilities to be responsibly and privately disclosed by sending an email to [support@tj-actions.online](mailto:support@tj-actions.online).
+
+### Public Vulnerability Disclosures
+
+For publicly disclosed security vulnerabilities, please **IMMEDIATELY** email [support@tj-actions.online](mailto:support@tj-actions.online) with the details for prompt action.
+
+Upon confirmation of a breach, reporters will receive full credit and recognition for their contribution. Please note, that we do not offer monetary compensation for reporting vulnerabilities.
+
+## Communication of Security Breaches
+
+We will utilize the [GitHub Security Advisory](https://github.com/tj-actions/changed-files/security/advisories) to communicate any security breaches. The advisory will be made public once a patch has been released to rectify the issue.
+
+We appreciate your cooperation and contribution to maintaining the security of our software. Remember, a secure community is a strong community.
