# First Steps
Once installed, here's how to get started with Gemini MCP Tool.
## Test Connection
```
/gemini-cli:ping "Hello from Gemini!"
```
## Basic File Analysis
Analyze a single file:
```
/gemini-cli:analyze @README.md summarize this
```
## Natural Language Usage
Just ask naturally:
- "Use gemini to explain this codebase"
- "Ask gemini to analyze the architecture"
- "Have gemini review this function"
## Sandbox Testing
Test code safely:
```
/gemini-cli:sandbox create a Python script that generates fibonacci numbers
```
