-The go to language for mathematicians!
+ARGON 3 is a math-driven programming language designed to make code easy to read and write. It's not meant to be fast, as it's interpreted. This specification should be used as a guideline, and is subject to change for later versions. Later updates for Argon 3 should be backwards compatible (where possible) with code designed for older versions of the interpreter.
 
-# Read Me
+## 📚 Features
 
-due to the project being in very early stages, the readme docs file is not yet being worked on. [read the specification to get an understanding of how the language will work.](spec.md)
+   - Easy to read and write: Argon 3 is designed with clarity of code in mind, making it easier for you and others to read and write code.
+   - Math-driven: Designed for mathematical computations, Argon 3 uses techniques and rules set in maths. It's designed to be easy for mathematicians to write and understand algorithms in.
+   - Interpreted: Argon 3 is an interpreted language, so you don't need to compile your code before running it.
+   - Cross-platform: Argon 3 can be run on any platform that has an interpreter for it.
+   - Lightweight: The Argon 3 interpreter is small and doesn't require a lot of system resources to run.
 
-# Licence
+## 💻 Installation
+As of now, Argon 3 does not have an installer. Feel free to clone this repo and run the `build` file for your plateform. the build will be found in `bin/Argon-v3(.exe)`.
+
+## 📖 Usage
+
+To use Argon 3, you can create a file with the .ar extension and write your code in it. Then, you can run your code using the interpreter. For example, if you have a file called example.ar, you can run it using the following command:
+
+```
+argon example.ar
+```
+
+## 🔍 Specification
+
+For a detailed specification of the Argon 3 language, please refer to [spec.md](spec.md).
+
+## 🚀 Example Code
+
+Here's an example of how to define a function in Argon 3:
+
+```javascript
+f(x) = x^2 + 2*x + 1
+log('f(10) =', f(10))
+```
+
+This code defines a function f(x) that calculates x^2 + 2*x + 1. It then calls the function with an argument of 10 and logs the result to the console.
+
+Please note that this example is subject to change as the specification is in beta and may be updated frequently.
