 If you are new to GitHub, please refer to [our blog](https://medium.com/optuna/optuna-wants-your-pull-request-ff619572302c) for more information.
 
 
+## Setup Development Environment
+
+First of all, fork Optuna MCP on GitHub. You can learn about fork in the [official documentation](https://docs.github.com/en/github/getting-started-with-github/fork-a-repo).
+
+After forking, download and install Optuna MCP on your computer as follows:
+
+```
+$ git clone [email protected]:YOUR_NAME/optuna-mcp.git
+$ cd optuna-mcp
+$ uv sync   # Install dependencies
+$ pwd       # Check the path to your optuna-mcp directory.
+/PATH/TO/optuna-mcp
+$ which uv  # Check the path to your uv binary.
+/PATH/TO/uv
+```
+
+After the installation, configure the MCP client (e.g., Claude Desktop) as explained in the [README.md](README.md#installation).
+Please fill the placeholders of path to your uv binary and optuna-mcp directory:
+
+```json
+{
+  "mcpServers": {
+    "Optuna": {
+      "command": "/PATH/TO/uv",

 # Optuna MCP Server
 
-The Optuna MCP Server is a [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) server to interact with Optuna APIs.
+A [Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) server that automates optimization and anlysis using [Optuna](http://optuna.org).
 
 <img width="840" alt="image" src="./examples/sphere2d/images/sphere2d-6.png" />
 
 ## Use Cases
 
-- Hyperparameter Optimization driven by LLMs
-- Interactive analysis of Optuna's optimization history
+The Optuna MCP Server can be used in the following use cases, for example.
 
+- Automated hyperparameter optimization by LLMs
+- Interactive analysis of Optuna's optimization results via chat interface
+- Optimize input and output of other MCP tools
 
-## Prerequisites
-
-Before starting the installation process, ensure to:
-
-1. Install `uv` from [Astral](https://docs.astral.sh/uv/getting-started/installation/)
-2. After installing `uv`, execute the command `uv python install 3.12` to install Python 3.12 or a newer version.
-3. Lastly, add the server to your MCP client configuration.
+For details, see the [Examples section](#examples).

+## Tools provided by Optuna MCP
+
+The Optuna MCP provides the following tools.
+Specifically, it offers primitive functions of Optuna such as Study, Trial, Visualization, and Dashboard.
