+After your changes, instead of running specific tests or linting specific files, run "pnpm format && pnpm lint && pnpm test". It means that you first format the code, then lint it, then test it, so that no part is broken after your changes.

+- After your changes, instead of running specific tests or linting specific files, run "pnpm format && pnpm lint && pnpm test". It means that you first format the code, then lint it, then test it, so that no part is broken after your changes.
+- Don't leave comments that don't add value
+- Do not duplicate code unless you have a very good reason to do so. It is important that the same logic is not duplicated multiple times
+- Before finishing the task and showing summary, always run "pnpm format && pnpm lint && pnpm test" at the root of the project to ensure that you don't finish with broken application.

+# Security Policy
+
+## Reporting Security Issues
+
+Thanks for helping make Donut Browser safe for everyone! ❤️
+
+We take the security of Donut Browser seriously. If you believe you have found a security vulnerability in Donut Browser, please report it to us through coordinated disclosure.
+
+**Please do not report security vulnerabilities through public GitHub issues, discussions, or pull requests.**
+
+Instead, please send an email to **contact at donutbrowser dot com** with the subject line "Security Vulnerability Report".
+
+Please include as much of the information listed below as you can to help us better understand and resolve the issue:
+
+- The type of issue (e.g., buffer overflow, injection attack, privilege escalation, or cross-site scripting)
+- Full paths of source file(s) related to the manifestation of the issue
+- The location of the affected source code (tag/branch/commit or direct URL)
+- Any special configuration required to reproduce the issue
+- Step-by-step instructions to reproduce the issue
+- Proof-of-concept or exploit code (if possible)
+- Impact of the issue, including how an attacker might exploit the issue
+- Your assessment of the severity level
+
+This information will help us triage your report more quickly.
+
+## What to Expect
+
+- **Response Time**: We will acknowledge receipt of your vulnerability report within 72 hours.
+- **Investigation**: We will investigate the issue and provide you with updates on our progress.
+- **Resolution**: We aim to resolve critical security issues as fast as possible, but no longer than in 30 days after the initial report.
+- **Disclosure**: We will coordinate with you on the timing of any public disclosure.
+
+## Contact
