+### HEADS UP! 🙂
+
+Argon v3.wasm is a fork of Argon v3 which has had parts rewritten for support in WebAssembly (WASM).
+
+It includes all the same features and functionality as Argon v3, but has been compiled to run efficiently on WebAssembly.
+
+Please note that Argon v3.wasm can only be compiled for use with WebAssembly.
+
+
+---
+
 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.
 
 ## 📚 Features
-   - 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.
+
-   - All numbers are stored as rational numbers, preventing precision errors.

 ## 💻 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(.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:
