## Application onboarding 

The first time you start OpenRAG, whether using the TUI or a `.env` file, you must complete application onboarding.

:::warning
Most values from onboarding can be changed later in the OpenRAG **Settings** page, but there are important restrictions.

The **language model provider** and **embeddings model provider** can only be selected at onboarding.
To change your provider selection later, you must [reinstall OpenRAG](/install#reinstall).

You must use the same provider for your language model and embedding model, unless you're using Ollama.
:::

Choose one LLM provider and complete only those steps:

    <Tabs groupId="Provider">
    <TabItem value="OpenAI" label="OpenAI" default>
    1. Enable **Get API key from environment variable** to automatically enter your key from the TUI-generated `.env` file.
    Alternatively, paste an OpenAI API key into the field.
    2. Under **Advanced settings**, select your **Embedding Model** and **Language Model**.
    3. To load 2 sample PDFs, enable **Sample dataset**.
    This is recommended, but not required.
    4. Click **Complete**.
    5. To complete the onboarding tasks, click **What is OpenRAG**, and then click **Add a Document**.
    Alternatively, click <Icon name="ArrowRight" aria-hidden="true"/> **Skip overview**.
    6. Continue with the [Quickstart](/quickstart).       

    </TabItem>
    <TabItem value="IBM watsonx.ai" label="IBM watsonx.ai">
    1. Complete the fields for **watsonx.ai API Endpoint**, **IBM Project ID**, and **IBM API key**.
    These values are found in your IBM watsonx deployment.
    2. Under **Advanced settings**, select your **Embedding Model** and **Language Model**.
    3. To load 2 sample PDFs, enable **Sample dataset**.
    This is recommended, but not required.
    4. Click **Complete**.
    5. To complete the onboarding tasks, click **What is OpenRAG**, and then click **Add a Document**.
    Alternatively, click <Icon name="ArrowRight" aria-hidden="true"/> **Skip overview**.

    <TabItem value="Ollama" label="Ollama">
    :::tip
    Ollama is not included with OpenRAG. To install Ollama, see the [Ollama documentation](https://docs.ollama.com/).
    :::   
    1. Enter your Ollama server's base URL address.
    The default Ollama server address is `http://localhost:11434`.
    OpenRAG automatically transforms `localhost` to access services outside of the container, and sends a test connection to your Ollama server to confirm connectivity.
    2. Select the **Embedding Model** and **Language Model** your Ollama server is running.
    OpenRAG retrieves the available models from your Ollama server.
    3. To load 2 sample PDFs, enable **Sample dataset**.
    This is recommended, but not required.
    4. Click **Complete**.
    5. To complete the onboarding tasks, click **What is OpenRAG**, and then click **Add a Document**.
    Alternatively, click <Icon name="ArrowRight" aria-hidden="true"/> **Skip overview**.
    6. Continue with the [Quickstart](/quickstart).
