 # Getting Started
 
-This `LitNodeClientNodeJs` is created solely to run on Node.js.
-
-The usual `checkAndSignAuthMessage` is not included in this package, so you need to add it manually to the constructor if you decide to use it on a browser, or with any custom auth callback.
+This package provides a Node.js-specific implementation of the Lit Protocol client, enabling server-side applications to interact with the Lit network. It offers optimized Node.js performance while maintaining all core Lit Protocol functionality, excluding browser-specific authentication which can be manually added if needed.
 
 ```js
 import * as LitJsSdkNodeJs from '@lit-protocol/lit-node-client-nodejs';

 # logger
 
-This library was generated with [Nx](https://nx.dev).
+This package provides a centralized logging utility for the Lit Protocol SDK, offering structured logging capabilities across all packages. It enables consistent log formatting, level-based filtering, and standardized error reporting throughout the Lit Protocol ecosystem.

 # Quick Start
 
-re-export of https://www.npmjs.com/package/nacl
+This package provides essential cryptographic operations for the Lit Protocol by re-exporting TweetNaCl.js (https://www.npmjs.com/package/nacl). It offers a lightweight implementation of the NaCl (pronounced "salt") cryptography library, enabling secure encryption, decryption, and digital signatures across the Lit Protocol ecosystem.

 # WASM
 
-Core lit utilities implemented in `Rust` and compiled to `WebAssembly` through `wasm-pack` implementations within this package wrap the compiled implementations from `rust` and provides functionality for converting the compiled artifact to a `base64` encoded string for binding to the generated bridge. the functionality contained within this package exposes the functinoality provided from the wasm utilities.
+This package provides high-performance cryptographic operations for the Lit Protocol by implementing core utilities in Rust and compiling them to WebAssembly. It enables efficient cross-platform execution of critical cryptographic functions while maintaining security and performance. The package handles the compilation process through wasm-pack and provides JavaScript bindings for seamless integration.
