-## Overview
+## Overview 📖
 
 SpectralIndices.jl is a Julia package for working with spectral indices commonly used in remote sensing and earth observation applications. It provides a convenient way to compute various spectral indices using Julia's high-performance capabilities.
 
-## Features
+## Features 🚀
 
-- Compute a wide range of spectral indices.
+- Computation for a wide range of spectral indices 
+- Computation support for `Float64`, `Float32` and `Float16` at index formula level to support fast computation for ML applications
 - Support for various data types, including but not limited to (see this [issue](https://github.com/awesome-spectral-indices/SpectralIndices.jl/issues/8) for an updated list and WIP)
   - [x] Arrays
   - [x] DataFrames
   - [x] YAXArrays
-- Flexible parameter input options.
-- Compatibility with multiple remote sensing platforms and sensors.

-### Direct computation
-SpectralIndices.jl also allows for direct computation using function calls:
-```julia
-result = NDVI(0.643, 0.175)
