 ragas is a framework that helps you evaluate your Retrieval Augmented Generation (RAG) pipelines. RAG denotes a class of LLM applications that use external data to augment the LLM’s context. There are existing tools and frameworks that help you build these pipelines but evaluating it and quantifying your pipeline performance can be hard.. This is were ragas (RAG Assessment) comes in
 
 ragas provides you with the tools based on the latest research for evaluating LLM generated text  to give you insights about your RAG pipeline. ragas can be integrated with your CI/CD to provide continuous check to ensure performance.

 ## 🧰 Metrics
 
 ### ✏️ Character based 
 
+Character based metrics focus on analyzing text at the character level.
+
 - **Levenshtein distance** the number of single character edits (additional, insertion, deletion) required to change your generated text to ground truth text.
 - **Levenshtein** **ratio** is obtained by dividing the Levenshtein distance by sum of number of characters in generated text and ground truth. This type of metrics is suitable where one works with short and precise texts.
