 # @qavajs/validation
 
-```
+A `@qavajs` library for validating data using plain English definitions. This package simplifies the process of creating validation functions by translating human-readable sentences into executable code.
+
+## Installation
+
+You can install the library using `npm`:
+
+```bash
 npm install @qavajs/validation
 ```
 
-@qavajs library that transforms plain english definition to validation functions
-
-Library supports following validations:
-* equal - not strict equal (==)
-* strictly equal - strict equal (===)
-* deeply equal - deep equal (chai eql)
-* contain - contain a substring
-* match - match a regular expression
-* above / greater than - greater than
-* below / less than - less than
-* have type - type validation
-* have members - validation if array/object have exact members
-* include members - validation if array/object includes members
-* have property - have property validation
-* match schema - match [ajv](https://www.npmjs.com/package/ajv) schema
-* case insensitive equal - not strict equal (==) with casting to lower case 
-
-All validations can be negated adding `not` word.
+## Supported Validations
+
+This library supports a variety of validation types, which can all be negated by adding the word `not`.
+
+### Equality & Comparison
+
+  - **`equal`**: Checks for non-strict equality (`==`).
+  - **`strictly equal`**: Checks for strict equality (`===`).
+  - **`deeply equal`**: Performs a deep comparison of object properties or array elements.
+  - **`case insensitive equal`**: Compares two values for non-strict equality after converting them to lowercase.
+  - **`contain`**: Verifies if a string contains a specific substring.
+  - **`include members`**: Checks if an array or object includes a specific set of members.
+  - **`have members`**: Validates if an array or object has an exact match of a specified set of members.
+  - **`have property`**: Ensures an object has a particular property.
+  - **`above`** / **`greater than`**: Checks if a value is greater than another.
+  - **`below`** / **`less than`**: Checks if a value is less than another.
+  - **`match`**: Validates if a string matches a regular expression.
+  - **`have type`**: Checks the type of a variable (e.g., `string`, `number`, `boolean`).
+  - **`match schema`**: Validates data against an [ajv](https://www.npmjs.com/package/ajv) schema, which is useful for complex object validation.
