<Note>
  **Python Version Requirements**
  
  CrewAI requires `Python >=3.10 and <3.13`. Here's how to check your version:
  ```bash
  python3 --version
  ```
  
  If you need to update Python, visit [python.org/downloads](https://python.org/downloads)
</Note>

# Setting Up Your Environment

Before installing CrewAI, it's recommended to set up a virtual environment. This helps isolate your project dependencies and avoid conflicts.

<Steps>
    <Step title="Create a Virtual Environment">
        Choose your preferred method to create a virtual environment:

        **Using venv (Python's built-in tool):**
        ```shell Terminal
        python3 -m venv .venv
        ```

        **Using conda:**
        ```shell Terminal
        conda create -n crewai-env python=3.12
        ```
    </Step>

    <Step title="Activate the Virtual Environment">
        Activate your virtual environment based on your platform:

        **On macOS/Linux (venv):**
        ```shell Terminal
        source .venv/bin/activate
        ```

        **On Windows (venv):**
        ```shell Terminal
        .venv\Scripts\activate
        ```

        **Using conda (all platforms):**
        ```shell Terminal
        conda activate crewai-env
        ```
    </Step>
</Steps>

# Installing CrewAI

Now let's get you set up! 🚀

<Steps>
    <Step title="Install CrewAI">
        Install CrewAI with all recommended tools using either method:
        ```shell Terminal
        pip install 'crewai[tools]'
        ```
        or
        ```shell Terminal
        pip install crewai crewai-tools
        ```

        <Note>
          Both methods install the core package and additional tools needed for most use cases.
        </Note>
    </Step>

    <Step title="Upgrade CrewAI (Existing Installations Only)">
        If you have an older version of CrewAI installed, you can upgrade it:
        ```shell Terminal
        pip install --upgrade crewai crewai-tools
        ```

        <Warning>
            If you see a Poetry-related warning, you'll need to migrate to our new dependency manager:
            ```shell Terminal
            crewai update
            ```
            This will update your project to use [UV](https://github.com/astral-sh/uv), our new faster dependency manager.
        </Warning>

        <Note>
            Skip this step if you're doing a fresh installation.
        </Note>
    </Step>

    <Step title="Verify Installation">
        Check your installed versions:
        ```shell Terminal
        pip freeze | grep crewai
        ```

        You should see something like:
        ```markdown Output
        crewai==X.X.X
        crewai-tools==X.X.X
        ```
        <Check>Installation successful! You're ready to create your first crew.</Check>

# Creating a New Project

<Tip>
  We recommend using the YAML Template scaffolding for a structured approach to defining agents and tasks.
</Tip>

<Steps>
  <Step title="Generate Project Structure">
    Run the CrewAI CLI command:
    ```shell Terminal
    crewai create crew <project_name>
    ```

    This creates a new project with the following structure:
    <Frame>
    ```
    my_project/
    ├── .gitignore
    ├── pyproject.toml
    ├── README.md
    ├── .env
    └── src/
        └── my_project/
            ├── __init__.py
            ├── main.py
            ├── crew.py
            ├── tools/
            │   ├── custom_tool.py
            │   └── __init__.py
            └── config/
                ├── agents.yaml
                ├── config.yaml
                └── tasks.yaml
    ```
    </Frame>
  </Step>

  <Step title="Install Additional Tools">
    You can install additional tools using UV:
    ```shell Terminal
    uv add <tool-name>
    ```

    <Tip>
      UV is our preferred package manager as it's significantly faster than pip and provides better dependency resolution.
    </Tip>
  </Step>

  <Step title="Customize Your Project">
    Your project will contain these essential files:

    | File | Purpose |
    | --- | --- |
    | `agents.yaml` | Define your AI agents and their roles |
    | `tasks.yaml` | Set up agent tasks and workflows |
    | `.env` | Store API keys and environment variables |
    | `main.py` | Project entry point and execution flow |
    | `crew.py` | Crew orchestration and coordination |
    | `tools/` | Directory for custom agent tools |

    <Tip>
      Start by editing `agents.yaml` and `tasks.yaml` to define your crew's behavior.
      Keep sensitive information like API keys in `.env`.
    </Tip>
  </Step>
</Steps>
