+title: System Requirement
+---
+
+Before proceeding with the installation and usage of GpgFrontend, it's crucial
+to understand the system requirements that ensure optimal performance. This
+section provides comprehensive details about the necessary software
+dependencies, hardware specifications, and the compatible operating systems.
+Meeting these requirements will ensure a smooth, efficient experience while
+using GpgFrontend.
+
+Please read the following subsections carefully to confirm that your system
+aligns with the recommended configurations.
+
+## Hardware
+
+While the specific hardware requirements largely depend on the size and
+complexity of the data you're working with, we generally recommend:
+
+A computer with at least 1 GB of RAM. However, 2 GB or more is preferable for
+smoother performance. The majority of these resources are allocated to your
+operating system, but around 100 MB of memory is needed to ensure the smooth
+running of GpgFrontend. At least 200 MB of free disk space for software
+installation. Additional space will be needed for ongoing work.
+
+Please note, these requirements are intended to be guidelines rather than strict
+rules. It's possible that GpgFrontend will work on lower-spec hardware, but for
+optimal performance, the above specifications are recommended.
+
+## Operating System
+
+GpgFrontend is compatible with major operating systems including Linux, macOS,
+and Windows. Specifically, it recommends Windows 7 and later, macOS 11 and
+later, and Ubuntu 20.04 LTS or other equivalent Linux distributions.
+
+## Software
+
+To ensure GpgFrontend functions seamlessly, it relies on the following software
+dependencies:
+
+- **Qt Framework:** GpgFrontend is developed using the Qt framework to offer a
+  rich user experience and cross-platform compatibility. The application
+  includes:
+
+  - **Qt6:** The primary build utilizes Qt6, ensuring a modern interface and
+    robust performance. Qt6 is included in the release packages for Linux,
+    macOS, and Windows, offering straightforward setup without additional
+    installations.
+  - **Qt5 Support for Windows:** Recognizing the need to accommodate users on
+    older versions of Windows, GpgFrontend also provides a Qt5-based version.
+    This variant ensures compatibility with earlier Windows environments,
+    extending the tool's accessibility and usability.
+
+- **GnuPG 2.2.0 or Higher:** GpgFrontend integrates with GnuPG for its
+  cryptographic operations, including encryption, decryption, and digital
+  signing. GnuPG (version 2.2.0 or newer) is a necessary component to leverage
+  the full capabilities of GpgFrontend. Please note, GnuPG 1.x versions are not
+  supported by GpgFrontend due to differences in functionality and support.
+  Users are encouraged to use GnuPG 2.x to ensure compatibility and secure
+  operations.
+
+By catering to a wide range of operating systems and ensuring backward
+compatibility with older Windows versions through Qt5 support, GpgFrontend
+strives to be as inclusive and accessible as possible.
+
+## Network
+
+Although not necessary for basic operation, an active Internet connection may be
+required for software updates and accessing online help resources.
+
+Please note that these are the minimal requirements that we tested, and actual
+requirements for your use case could be higher, especially for large datasets.
