 ## Overview
 
-DeciMojo provides a comprehensive decimal and integer mathematics library for Mojo, delivering exact calculations for financial modeling, scientific computing, and applications where floating-point approximation errors are unacceptable. Beyond basic arithmetic, the library includes advanced mathematical functions with guaranteed precision.
+DeciMojo provides an arbitrary-precision decimal and integer mathematics library for Mojo, delivering exact calculations for financial modeling, scientific computing, and applications where floating-point approximation errors are unacceptable. Beyond basic arithmetic, the library includes advanced mathematical functions with guaranteed precision.
 
 The core types are:
 
-- A 128-bit fixed-point decimal implementation (`Decimal`) supporting up to 29 significant digits with a maximum of 28 decimal places[^fixed]. It features a complete set of mathematical functions including logarithms, exponentiation, roots, and trigonometric operations.
+- A 128-bit fixed-point decimal implementation (`Decimal`) supporting up to 29 significant digits with a maximum of 28 decimal places[^fixed]. It features a complete set of mathematical functions including logarithms, exponentiation, roots, etc.
+- An arbitrary-precision decimal implementation `BigDecimal` allowing for calculations with unlimited digits and decimal places[^arbitrary].
 - A base-10 arbitrary-precision signed integer type (`BigInt`) and a base-10 arbitrary-precision unsigned integer type (`BigUInt`) supporting unlimited digits[^integer]. It features comprehensive arithmetic operations, comparison functions, and supports extremely large integer calculations efficiently.
-- An arbitrary-precision decimal implementation `BigDecimal` allowing for calculations with unlimited digits and decimal places[^arbitrary]. It is currently under active development.
 
 This repository includes [TOMLMojo](https://github.com/forfudan/decimojo/tree/main/src/tomlmojo), a lightweight TOML parser in pure Mojo. It parses configuration files and test data, supporting basic types, arrays, and nested tables. While created for DeciMojo's testing framework, it offers general-purpose structured data parsing with a clean, simple API.
