    Go to github.com
    Click "Sign in"
    Enter credentials
""")
```

**CSV:**

```csv theme={null}
Step,Action,Expected Result

```

## Guidelines

* **Be specific**: "Click the blue Submit button" > "Click submit"
* **One action per step**: Easier to debug
* **Include verification**: "Click Submit. Verify success message appears."
