# Creating skills for Alice

As an example, we'll create a skill called <q>Parrot</q>, which repeats everything a user writes or says. We implement our example in two programming languages: Python and Node.js.

To add skills based on a [function](../concepts/function.md) to Alice:

1. [Prepare the skill code](#prepare-code).
1. [Create a function](#create-function).
1. [Create a version of the function](#create-version).
1. [Add the function link to Alice's skill](#add-link).
1. [Test the skill](#test).

More about [developing Alice's skills](https://yandex.ru/dev/dialogs/alice/doc/development-docpage/#test__dev-cycle).

## Prepare the code for Alice's skill {#prepare-code}

To create [versions](../../functions/concepts/function.md#version) of functions, you can use one of the [code upload formats](../../functions/concepts/function.md#upload). As an example, we'll upload the code in a ZIP archive.

{% list tabs %}

- Python
    1. Download a sample file from GitHub: [parrot.py](https://github.com/yandex-cloud/examples/blob/master/serverless/functions/alice/python/parrot/parrot.py).
    1. Create a ZIP archive named `parrot-py.zip` with the `parrot.py` file.

- Node.js
    1. Download a sample file from GitHub: [index.js](https://github.com/yandex-cloud/examples/blob/master/serverless/functions/alice/nodejs/parrot/index.js).
    1. Create a ZIP archive named `parrot-js.zip` and add the `index.js` file.

{% endlist %}

## Create a function {#create-function}

Once created, the function will only contain information about itself, like its name, description, and unique ID. The skill's code will be added to the function when you [create a version](#create-version).

1. In [management console]({{ link-console-main }}), select the folder where you want to create your function.

1. Click **Create resource**.

1. Choose **Function**.

1. Enter a function name.

    {% include [name-format](../../_includes/name-format.md) %}

1. Click **Create**.

## Create the version of the function {#create-version}

Choose the programming language and create a [version of the function](../concepts/function.md#version).

{% list tabs %}

- Python
  1. In the [management console]({{ link-console-main }}), open **{{ sf-name }}** in the folder where you want to create the function version.
  1. Select the function to create the version for.
  1. Under **Latest version**, click **Create in editor**.
  1. Set the version parameters:
      - **Runtime environment:** `python37`.
      - **Timeout, seconds:** 2.
      - **RAM:** 128 MB.
      - **Service account:** Not selected.
  1. Prepare the function code:
      - **Method:** ZIP archive.
      - **File:** `parrot-py.zip`.
      - **Entry point:** `parrot.handler`.
  1. Click **Create version**.

- Node.js
  1. In the [management console]({{ link-console-main }}), open **{{ sf-name }}** in the folder where you want to create the function version.
  1. Select the function to create the version for.
  1. Under **Latest version**, click **Create in editor**.
  1. Set the version parameters:
      - **Runtime environment:** `nodejs12`.
      - **Timeout, seconds:** 2.
      - **RAM:** 128 MB.
      - **Service account:** Not selected.
  1. Prepare the function code:
      - **Method:** ZIP archive.
      - **File:** `parrot-js.zip`.
      - **Entry point:** `index.handler`.
  1. Click **Create version**.

{% endlist %}

## Add the function link to Alice's skill {#add-link}

1. Go to Alice's skill page in your [dashboard](https://dialogs.yandex.ru/developer/).

1. Open the **Settings** tab.

1. Under **Backend**, select **Function in Yandex.Cloud**.

1. Select the desired function from the drop-down list.

    {% note warning %}

    The list shows the functions that you're allowed to view. To attach a function to a skill, you need permission to launch the function. This permission is part of the [{{ roles-functions-ivoker }}](../security/index.md#serverless-functions-invoker), [{{ roles-editor}}](../security/index.md#editor), and higher roles.

    {% endnote %}

1. Click **Save** at the bottom of the page to save changes.

## Test the skill {#test}

1. Open the **Testing** tab on the skill page in your [dashboard](https://dialogs.yandex.ru/developer/).
1. If everything is set up correctly, the **Chat** section will display a message inviting you to start a conversation: `Hello! I'll repeat anything you say to me.`.
1. Send a message and make sure the response is the same.
