+The desktop version of privacy.sexy features advanced error handling capabilities.
 In scenarios where script execution or storage encounters failure, the desktop application initiates automated troubleshooting and self-healing processes.
-It also guides users through potential issues with filesystem or third-party software, such as antivirus interventions.
+It employs robust and reliable execution strategies, including self-healing mechanisms, and provides guidance and troubleshooting information to resolve issues effectively.
-Specifically, the application is capable of identifying when antivirus software blocks or removes a script, providing users with tailored error messages
+This proactive error handling and user guidance enhances the application's security and reliability.
-and detailed resolution steps. This level of proactive error handling and user guidance enhances the application's security and reliability,
+
-offering a feature not achievable in the web version due to browser limitations.
+### Native dialogs
+
+The desktop version uses native dialogs, offering more features and reliability compared to the browser's file system dialogs.
+These native dialogs provide a more integrated and user-friendly experience, aligning with the operating system's standard interface and functionalities.

+# System Requirements for the Desktop Version
+
+The following system requirements are the official ones for the desktop version.
+While we have tested and confirmed these requirements, the application might also work on other
+systems or configurations that haven't undergone official testing.
+
+## Windows
+
+- **Version:** Windows 10 and later.
+- **Processor:** Intel Pentium 4 or later.
+- **Architecture:** 64-bit (x86-64), ARM (ARM64).
+
+> **⚠️ Compatibility Note:**
+> ARM version is only compatible with Windows 11 and later.
+> It runs non-natively, leading to slower performance due to emulation [1].
+
+## macOS
+
+- **Version:** macOS Catalina (10.15) and later.
+- **Architecture:** Intel-based (x86-64), Apple silicon (ARM64).
+
+## Linux
+
+- **Version:** Ubuntu 18.04 and later, Fedora 32 and later, and Debian 10 and later.
+- **Processor:** Intel Pentium 4 or later.
+- **Architecture:** 64-bit (x86-64).
+
+## References
+
+System requirements reflect Electron's platform capabilities [2] and Chromium's recommended configurations [3].
