-## How to use it?
+## How to Perform Symmetric Encryption
 
-Symmetric encryption is initiated when you click the 'Encrypt' button without
-selecting any key in the Key Toolbox. For this type of encryption, a password
-must be established for the encryption process. Subsequently, to decrypt the
-data, you will need to provide the same password that was used during the
-encryption phase.
+Performing symmetric encryption with GpgFrontend is a straightforward process.
+Follow these steps to encrypt your data using a password:
+
+1. **Prepare Your Data**:
+
+   - Start by opening GpgFrontend and entering the text you want to encrypt in
+     the text editor area. You can create a new tab through the "New" option if
+     needed.
+
+2. **Initiate Encryption**:
+
+   - Click the 'Encrypt' button in the Operations Bar at the top of the
+     interface. This button is represented by a padlock icon with the label
+     "Encrypt".
+
+3. **No Key Selected**:
+
+   - If no key is selected in the Key Toolbox, a prompt will appear asking if
+     you want to encrypt with a symmetric cipher using a passphrase. Click "OK"
+     to proceed.
+
+4. **Set a Password**:
+
+   - Enter a strong, unique password in the prompt that appears. This password
+     will be used to encrypt your data. Ensure that the password is complex and
+     secure, as it will be required to decrypt the data later.
+
+5. **Encryption Process**:
+
+   - GpgFrontend will use the provided password to encrypt your data,
+     transforming the plaintext into ciphertext. The resulting encrypted message
+     will be displayed in the text editor area.
+
+6. **Save or Share Encrypted Data**:
+   - You can now save the encrypted message to a file or share it with others.
+     Remember, the recipient will need the exact password used during encryption
+     to decrypt the data.
+
+By following these steps, you can easily encrypt your data using symmetric
+encryption in GpgFrontend. This method is ideal for scenarios where you need to
+secure data with a password without managing public and private keys.

+## How to Decrypt Symmetric Encryption?
+
+Decrypting symmetrically encrypted data with GpgFrontend is straightforward and
+similar to decrypting data encrypted with asymmetric encryption. Follow these
+steps:
+
+1. **Copy the Ciphertext**:
+
+   - First, ensure that you have the ciphertext (the encrypted message) copied
+     to your clipboard. The ciphertext should be in the format typically
+     generated by GnuPG, enclosed in `-----BEGIN PGP MESSAGE-----` and `-----END
+PGP MESSAGE-----` tags.
+
+2. **Paste the Ciphertext into the Text Editor**:
+
+   - Open GpgFrontend and paste the ciphertext into the text editor area. You
+     can do this by creating a new tab through the "New" option if needed.
+
+3. **Click the Decrypt Button**:
+
+   - Click the 'Decrypt' button in the Operations Bar at the top of the
+     interface. This button is represented by a key icon with the label
+     "Decrypt".
+
+4. **Enter the Password**:
+
+   - A prompt will appear asking for the password that was used to encrypt the
+     data. Enter the correct password and confirm.
+
+5. **Decryption Process**:
+   - GpgFrontend will use GnuPG to recognize the type of encryption used and the
+     corresponding key. If the password is correct, the software will decrypt
+     the ciphertext and display the readable plaintext in the text editor area.
+
+By following these steps, you can efficiently decrypt any symmetrically
+encrypted data using GpgFrontend. The software's ability to automatically
+recognize the encryption type and key ensures a seamless decryption process,
+making it easy to access your encrypted information securely.
