 ## Overview of Evol-Instruct
 
-[Evol-Instruct](https://github.com/nlpxucan/evol-instruct) is a novel method using LLMs instead of humans to automatically mass-produce open-domain instructions of various difficulty levels and skills range, to improve the performance of LLMs. You can easily embark on your own evolutionary journey with the [Evol Script](https://github.com/nlpxucan/WizardLM/tree/main/Evol-Instruct) we provide.
