+
+## Understanding GpgFrontend
+
+**What is GpgFrontend?** GpgFrontend is a user-friendly, cross-platform tool
+designed to facilitate the use of OpenPGP encryption, making it easier for
+individuals to protect their privacy and secure their communications.
+
+**What can I do with GpgFrontend?** Beyond basic encryption and decryption,
+GpgFrontend supports digital signatures to verify the integrity and origin of
+messages. Users can manage and generate key pairs, encrypt files and emails, and
+sign their communications for added security.
+
+**How can I obtain and start using GpgFrontend?** You can download the latest
+version of GpgFrontend from its GitHub repository. Visit [GpgFrontend's
+Downloads Page](https://www.gpgfrontend.bktus.com/#/downloads) to find the most
+recent release. Installation is straightforward: just follow the ReadME
+instructions to set it up.
+
+## OpenPGP and GnuPG Explained
+
+**How do OpenPGP and GnuPG relate?** OpenPGP serves as a standardized protocol
+for encrypting and decrypting data, which GpgFrontend supports. GnuPG, or GPG,
+implements the OpenPGP standard, providing the necessary cryptographic
+functions. GpgFrontend leverages GnuPG for operations like encryption,
+decryption, and key management.
+
+**Which operating systems does GpgFrontend support?** GpgFrontend is a
+cross-platform application that supports Windows, macOS, and Linux, making it
+accessible to nearly all users for their privacy and data protection needs.
+
+## Troubleshooting GnuPG Installation Issues
+
+**Encountering 'GnuPG not installed correctly'?** This issue typically arises
+when GpgFrontend cannot locate GnuPG on your system. Here are steps to address
+this based on your operating system:
+
+### For macOS Users
+
+- **Install GnuPG for OSX** from
+  [here](https://sourceforge.net/p/gpgosx/docu/Download/), or install
+  GpgFrontend using Homebrew with `brew install --cask gpgfrontend`.
+- If GnuPG is installed in a custom location, please tell GpgFrontend where the
+  gpgconf binary it is at GnuPG Controller.
+
+### For Linux Users
+
+- Install GnuPG via your package manager (apt, yum, etc.).
+- If GnuPG is installed in a custom location, please tell GpgFrontend where the
+  gpgconf binary it is at GnuPG Controller.
+
+### For Windows Users
+
+- The latest GpgFrontend versions include GnuPG. It's recommended to download
+  the most recent GpgFrontend version.
+- Alternatively, download GnuPG from
+  [here](https://www.gnupg.org/ftp/gcrypt/binary/gnupg-w32-2.4.0_20221216.exe)
+  and reinstall if necessary.
+
+### Additional Assistance
+
+- For more detailed guidance, refer to the quick start manual available at
+  [Quick Start Guide](quick-start.md).
+
+## Reporting Bugs and Contributing
+
+**Found a bug?** If you encounter any issues with GpgFrontend, please report
+them via the GitHub repository. You can also contact me directly if you're not
+on GitHub; see the [Contact](contract.md) section for details.
+
+**Interested in contributing?** Feel free to modify GpgFrontend's code and
+submit a Pull Request with your enhancements. You can also send patches via
+email if you prefer to contribute anonymously.
+
+## Why the Need for GnuPG?
+
+**Importance of Installing GnuPG** GpgFrontend itself does not handle direct
+encryption or decryption; it requires GnuPG for these operations. This design
+choice ensures higher security, allowing users to rely on their own verified
+version of GnuPG.
+
+## Understanding BETA Versions
+
+**What does "BETA" signify in a release?** A "BETA" label indicates that the
+version may not have undergone comprehensive testing, particularly for new
+modules. While beta versions are carefully evaluated post-release, and stable
+versions are published when ready, the aim is to avoid beta releases from
+version 2.0.0 onwards, barring exceptional circumstances.
+
+## Security and Privacy
+
+**How does GpgFrontend ensure my communications are secure?** GpgFrontend uses
+GnuPG to implement the OpenPGP standard, securing your data with robust
+encryption algorithms to prevent unauthorized access. It supports public and
+private key encryption methods, ensuring only intended recipients can decrypt
+and read your messages.

+title: Getting Started with GpgFrontend
+sidebar:
+  label: Getting Started
+  order: 2
+---
+
+Welcome to GpgFrontend, the cross-platform, OpenPGP encryption tool designed for
+simplicity and security. This guide will walk you through the installation
+process tailored to your operating system, ensuring you can start securing your
+communications as quickly and efficiently as possible.
+
+## Before You Begin: Prerequisites
+
+**Note for Windows or macOS users who utilize Homebrew: You may skip this
+prerequisites section.**
+
+GpgFrontend leverages the robust functionalities of GnuPG for encryption,
+decryption, and key management. It is crucial to have GnuPG installed on your
+device to make full use of GpgFrontend. Starting from version 2.0, GnuPG
+operates on modular components for enhanced functionality, requiring proper
+integration with your system.
+
+Be aware, due to GnuPG's inability to function within an App Sandbox,
+GpgFrontend is not available through the Apple Store.
+
+For Linux users, most contemporary distributions come with GnuPG 2.0
+pre-installed. Check your GnuPG version with `gpg --version` in your terminal.
+It is advisable to upgrade to GnuPG version 2.2 or later for optimal performance
+and compatibility.
+
+## Installation & Execution Guide

+## Basic Operations with GpgFrontend
+
+After successfully installing GpgFrontend, you're ready to dive into the world
+of encryption and secure communication. This guide will walk you through some
+fundamental operations to get you started.
+
+### Generating Your First Key Pair
+
+1. Open GpgFrontend: Launch the application.
+2. Access Key Management: Navigate to the "Key Management" section.
+3. Generate Key Pair: Look for an option to "Generate" a new key pair.
+4. Fill in your details, such as name and email, and choose your desired key
+   type and size. You can also add a comment if you wish.
+5. Set an expiration date for the key, or choose 'Never Expire' if you prefer.
+6. Create a passphrase for your key to ensure its security. Remember to use a
+   strong passphrase that you won't forget.
+7. Once all details are filled in, click 'OK' to generate your key pair.
+
+### Encrypting
+
+1. **Write a Message:** Start by writing a message in the main text area of
+   GpgFrontend.
+2. **Choose Recipient:** Select the public key of the message's recipient. If
+   you're practicing, you can select your own public key.
+3. **Encrypt:** With the recipient's public key selected, click on the "Encrypt"
+   option. The text will be encrypted, making it readable only by the selected
+   recipient.
+
+### Decrypting
+
+1. **Receive an Encrypted Message:** Copy the encrypted message into
+   GpgFrontend's main text area.
+2. **Decrypt:** Click on the "Decrypt" option. If the message was encrypted with
+   your public key, you would need to enter the password for your private key to
+   decrypt it.
+
+### Signing
+
+1. **Create a Message:** Type your message in the text area.
+2. **Sign:** Choose the "Sign" option and select your private key. Enter your
+   key's password to sign the message. This adds a digital signature that
+   verifies you as the message's sender.
+
+### Verifying
+
+1. **Receive a Signed Message:** Paste the signed message into GpgFrontend.
+2. **Verify:** Click on "Verify" to check the signature. If the signature
+   matches the sender's public key, GpgFrontend will confirm the message's
+   integrity and authenticity.
+
+### Key Management and Sharing
+
+#### Exporting and Sharing Your Public Key
+
+1. Go to 'Manage Keys'.
+2. Select your key pair and choose 'Export Key'.
+3. Save your public key to a file or copy it to the clipboard to share it with
+   others.
+
+#### Importing a Public Key
+
+To communicate securely with someone else, you need their public key. Click
+'Import key'. You can import a key file or copy and paste the public key
+directly. After importing, the public key will appear in your keyring, ready for
+use.
+
+### Exchanging Public Keys with Friends
+
+1. **Export Your Public Key:** From the "Key Management" section, find the
+   option to export your public key. Save it as a file or copy it to your
+   clipboard.
+2. **Share Your Public Key:** Send your public key to your friend via email,
+   messaging app, or any secure channel you prefer.
+3. **Import Your Friend's Public Key:** When your friend sends you their public
+   key, import it into GpgFrontend using the "Import" option in the "Key
+   Management" section.
+
+By exchanging public keys, you establish a secure channel for encrypted
+communication. Only the holder of the corresponding private key can decrypt
+messages encrypted with a public key, ensuring privacy and security in your
+communications.
+
