 # Python Risk Identification Tool for generative AI (PyRIT)
 
-The Python Risk Identification Tool for generative AI (PyRIT) is an open
-access automation framework to empower security professionals and ML
-engineers to red team foundation models and their applications.
+The Python Risk Identification Tool for generative AI (PyRIT) is an open source
+framework built to empower security professionals and engineers to proactively
+identify risks in generative AI systems.
 
-## Introduction
-
-PyRIT is a library developed by the AI Red Team for researchers and engineers
-to help them assess the robustness of their LLM endpoints against different
-harm categories such as fabrication/ungrounded content (e.g., hallucination),
-misuse (e.g., bias), and prohibited content (e.g., harassment).
-
-PyRIT automates AI Red Teaming tasks to allow operators to focus on more
-complicated and time-consuming tasks and can also identify security harms such
-as misuse (e.g., malware generation, jailbreaking), and privacy harms
-(e.g., identity theft).​
-
-The goal is to allow researchers to have a baseline of how well their model
-and entire inference pipeline is doing against different harm categories and
-to be able to compare that baseline to future iterations of their model.
-This allows them to have empirical data on how well their model is doing
-today, and detect any degradation of performance based on future improvements.
-
-Additionally, this tool allows researchers to iterate and improve their
-mitigations against different harms.
-For example, at Microsoft we are using this tool to iterate on different
-versions of a product (and its metaprompt) so that we can more effectively
-protect against prompt injection attacks.
