# Quickstart

> Create your first LLM function calling tool in minutes

<Steps>
  <Step title="Install Yomo CLI">
    ```sh theme={null}
    curl -fsSL "https://get.yomo.run" | sh
    ```
  </Step>

  <Step title="Initialize a LLM Function">
    ```sh theme={null}
    yomo init tool-get-weather
    ```

    an example serverless llm function will be created in the `tool-get-weather` directory:

    ```sh theme={null}
    $ tree tool-get-weather
    drwxr-xr-x@   - c3ylabs 15 Apr 10:00 tool-get-weather
    .rw-r--r--@  53 c3ylabs 15 Apr 10:00 ├── .env
    .rw-r--r--@  32 c3ylabs 15 Apr 10:00 ├── .gitignore
    .rw-r--r--@ 391 c3ylabs 15 Apr 10:00 ├── package.json
    .rw-r--r--@ 14k c3ylabs 15 Apr 10:00 ├── pnpm-lock.yaml
    drwxr-xr-x@   - c3ylabs 15 Apr 10:00 ├── src
    .rw-r--r--@ 612 c3ylabs 15 Apr 10:00 │   └── app.ts
    .rw-r--r--@ 266 c3ylabs 15 Apr 10:00 └── tsconfig.json
    ```
  </Step>

  <Step title="Start YoMo Server and expose MCP server">
    Create your `yomo.config.yaml` file in the root directory of your project. This file is used to configure the YoMo server and specify the MCP server settings.

    ```yaml theme={null}
    name: ai-zipper
    host: 0.0.0.0
    port: 9000

    bridge:
      mcp:
        server:
          addr: localhost:9001
      ai:
        server:
          addr: localhost:9000
          provider: openai

        providers:
          openai:
            api_key: sk-proj-xxxxx
            model: gpt-4.1
    ```

    ```sh theme={null}
    yomo serve -c yomo.config.yaml
    ```

    The output will be like:

    ```sh theme={null}
    3:14PM INF Starting YoMo Zipper...
    3:14PM INF using config file service=zipper zipper_name=ai-zipper file_path=./yomo.config.yaml
    3:14PM INF listening SIGUSR1, SIGUSR2, SIGTERM/SIGINT...
    3:14PM INF register LLM providers num=11
    3:14PM INF start AI Bridge service service=llm-bridge addr=localhost:9000 provider=vllm
    3:14PM INF zipper is up and running service=zipper zipper_name=ai-zipper zipper_addr=[::]:9000 pid=34882 quic="[v1 v2]" auth_name=[none]
    ```
  </Step>

  <Step title="Start the serverless LLM function">
    ```sh theme={null}
    yomo run
    ```
