 # ResilientLLM
 
-A simple but robust LLM integration layer designed to ensure reliable, seamless interactions across multiple APIs by intelligently handling failures and rate limits.
+A minimalist but robust LLM integration layer designed to ensure reliable, seamless interactions across multiple LLM providers by intelligently handling failures and rate limits.
+
+## Why Use ResilentLLM
+
+This library solves challenges in building production-ready AI Agents due to
+
+- Unstable network conditions
+- Inconsistent error handling
+- Unpredictable LLM API rate limit errors
+
+### Key Features
+
+- **Rate limiting**: You don’t need to calculate tokens or manage rate limits yourself
+- **Token estimation**: The number of LLM tokens is estimated for each request and enforced.
+- **Retries, backoff, and circuit breaker**: All are handled internally by the `ResilientOperation`.
+
+## Installation

+```bash
+npm i resilient-llm
+```

-
-- **Rate limiting is automatic**: You don’t need to pass token counts or manage rate limits yourself.
-- **Token estimation**: The number of LLM tokens is estimated for each request and enforced.

 ## Motivation
 
 ResilientLLM is a resilient, unified LLM interface featuring circuit breaker, token bucket rate limiting, caching, and adaptive retry with dynamic backoff support.
