-# Basic Concepts
+# Fundamental Concepts
 
-If you don't know GPG, or PGP, you may need to learn some basic concepts here
-before using Gpg Frontend. This reduces the chance of you making mistakes, such
-as distributing your private key to the world.
+If you're unfamiliar with GPG or PGP, it would be beneficial to learn some
+fundamental concepts before using GpgFrontend. This can help prevent potential
+mistakes, such as accidentally sharing your private key.
 
-## The most basic concepts you must know
+## Essential Concepts
 
-To begin using GPG, you must first generate a key pair, which can be thought of
-as a key ring. Each key pair includes at least two keys: a public key and a
-corresponding private key. Together, these keys form a key pair. It is possible
-for a key pair to include multiple public keys and their corresponding private
-keys, but this will be explained later.
+Before you start using GPG, you need to generate a key pair, analogous to a key
+ring. Each key pair comprises at least two keys: a public key and a
+corresponding private key. It is possible for a key pair to contain multiple
+public keys and their associated private keys, which we'll discuss later.
 
-The public key can be shared with others, allowing them to encrypt information
-they wish to send to you. The private key must be kept secure, as its disclosure
-would render your encryption ineffective.
+The public key can be shared with others, allowing them to encrypt data they
+want to send you. Conversely, the private key should remain confidential since
+its exposure can compromise your encryption.
 
-It is important to understand that the public key is used for encryption and
-that any ciphertext encrypted using your public key can only be decrypted using
-the corresponding private key of your key pair. This process relies on
-cryptographic principles and is trustworthy unless your private key is known to
-someone else. The reverse process is also valid: you can encrypt a message using
-your private key and someone else can decrypt it using your public key. This
-process establishes a mechanism for signing and verifying information.
-Information encrypted with the private key can be considered a signature, and
-others can use the public key to verify that the signature is valid.
+It's vital to understand that the public key is used for encryption, and the
+ciphertext encrypted with your public key can only be decrypted using your key
+pair's corresponding private key. This process is based on cryptographic
+principles and is reliable unless your private key gets compromised. Similarly,
+you can encrypt a message with your private key, and someone else can decrypt it
+using your public key, establishing a signature verification mechanism.
 
-For most users, it is not necessary to understand the cryptography behind GPG,
-but it is helpful to remember the basic principles described above. For those
-interested in learning more, further reading is recommended.
+While understanding the underlying cryptography of GPG isn't necessary for most
+users, remembering these basic principles can be beneficial. 
 
-## Multiple pairs of public and private keys in a key pair
+## Multiple Pairs of Public and Private Keys in a Key Pair
 
-In a key pair, there is always at least one public-private key pair, but there
-is no limit to the maximum number of pairs. It is possible to generate
-additional pairs of public and private subkeys and add them to the key pair.
-However, it should be noted that the newly added subkeys are identical to the
-original pair, as each pair consists of one public key and one private key,
-which we refer to as the primary key pair.
+A key pair always contains at least one public-private key pair, but there's no
+maximum limit. It's possible to generate additional public and private subkeys
+to add to the key pair. Each pair consists of one public key and one private
+key, which we refer to as the primary key pair.
 
-Users can specify the purpose of each subkey pair. For instance, the first key
-pair can be used for encryption and decryption, the second for signing and
-verification, and the third for both encryption/decryption and
-signing/verification. It is important to specify the intended usage when
+Users can specify the purpose of each subkey pair. For instance, the first pair
+can be used for encryption and decryption, the second for signing and
+verification, and so forth. It's important to define the intended usage when
 generating subkeys.
 
-The master key is automatically generated when the key pair is created, and
-users can add subkeys as needed.
+The primary key is automatically generated when creating the key pair, and users
+can add subkeys as needed. When generating the primary key or subkeys, users can
+select algorithms such as RSA or DSA.
 
-When generating the master key or subkeys, users can select algorithms such as
-RSA or DSA. It is not necessary to understand the underlying principles of these
-algorithms. However, it is important to note that subkeys generated by certain
-algorithms may only perform specific processes, such as signing and
-verification, and cannot perform others, such as encryption and decryption.
-Additionally, for RSA, users can choose the key length when using the algorithm.
+## The First Pair of Public and Private Keys in a Key Pair (Primary Key)
 
-## The first pair of public and private keys in a key pair (primary key)
+The initial public-private key pair (primary key) in a key pair is crucial as
+all subsequent subkeys are tied to it. If the primary key is compromised, they
+could generate subkeys based on that information and impersonate the key owner.
 
-The initial public-private key pair (master key) in a key pair is crucial, as
-all subsequent sub-keys are linked to it. If someone were to obtain the master
-key (including both the public and private key information), they could generate
-sub-keys based on that information and use them to impersonate the key owner and
-communicate with others.
-
-Therefore, it is essential that the private key of the master key is kept
-confidential, while the public key can be shared with others. If the private key
-of the master key is compromised, it renders the entire key pair vulnerable and
-must be immediately discontinued.
+Therefore, it's crucial to keep the primary key's private key confidential,
+while the public key can be shared. If the private key of the primary key is
+compromised, it makes the entire key pair vulnerable and its use should be
+immediately discontinued.

+One of the unique features of GpgFrontend is its cross-platform capability.
+Depending on your operating system, the installation process might vary.

+**If you are a Windows or macOS user with Homebrew, you can skip this section.**
 
-GpgFrontend runs dependent on basic functions provided by GnuPG, so you need to install GnuPG before you can run
-GpgFrontend. Why does GpgFrontend require users to install GnuPG separately? Starting with GnuPG 2.0, GPG relies on
-separate modules to do all of its functions. This requires that when using GPG, these modules all need to be in the
-correct location on your operating system so that the GPG can find them.
