-# Create Custom LLM Tool
-In this document, we will guide you through the process of developing a tool with `custom_llm` type which can connect to a customized large language model with prompt.

-A Custom LLM is a large language model fine-tuned by yourself. If you find it has good performance and is useful, then you can follow this guidance to make it a tool so that it can be shared with others to increase its impact.
+# Customize an LLM Tool
+In this document, we will guide you through the process of customizing an LLM tool, allowing users to seamlessly connect with a large language model while fine-tuning their prompts using a `PromptTemplate`.
 
 ## Prerequisites
 - Please ensure that your [Prompt flow for VS Code](https://marketplace.visualstudio.com/items?itemName=prompt-flow.prompt-flow) is updated to version 1.2.0 or later.

+## How to customize an LLM tool
 Here we use [an existing tool package](https://github.com/microsoft/promptflow/tree/main/examples/tools/tool-package-quickstart/my_tool_package) as an example. If you want to create your own tool, please refer to [create and use tool package](create-and-use-tool-package.md).  
 
 1. Develop the tool code as in [this example](https://github.com/microsoft/promptflow/blob/main/examples/tools/tool-package-quickstart/my_tool_package/tools/tool_with_custom_llm_type.py).
-- Add a `CustomConnection` input to the tool, which is used to authenticate and establish a connection to the customized large language model.
-- Add a `PromptTemplate` input to the tool, which serves as an argument to be passed into the customized large language model.
