 ## Introduction
 
 SlowKey is a cutting-edge [Key Derivation Function](https://en.wikipedia.org/wiki/Key_derivation_function) (KDF) tool designed to enhance cryptographic security in various applications, from securing sensitive data to protecting user passwords. At its core, SlowKey leverages the power of five renowned cryptographic algorithms: [Scrypt](https://en.wikipedia.org/wiki/Scrypt), [Argon2](https://en.wikipedia.org/wiki/Argon2), [Balloon Hash](https://en.wikipedia.org/wiki/Balloon_hashing), [SHA2](https://en.wikipedia.org/wiki/SHA-2), and [SHA3](https://en.wikipedia.org/wiki/SHA-3), each selected for its unique strengths in ensuring data integrity and security.
@@ -29,7 +54,7 @@ The SlowKey Key Derivation Scheme is defined as follows:
 - `Argon2id(data, salt)`: Function to derive a key using Argon2id KDF with `data` and `salt`.
 - `BalloonHash(data, salt)`: Function to derive a key using Balloon Hash KDF with `data` and `salt`.
 
-### Inputs
+### Input
 
 - `password`: User's password.
 - `salt`: Unique salt for hashing. Please note that the salt must be `16` bytes long, therefore shorter/longer salts will be SHA512 hashed and then truncated into `16` bytes.
