# Books

Learn how to extend your automation functionality in Kognitos with Books.

### What is a Book? <a href="#learning-books-1" id="learning-books-1"></a>

A **book** is a set of related automation procedures *(actions)* that can extend an agent’s capabilities. Think of it as a toolkit that teaches your agent **new skills**.

### Different Uses for Books

Each book contains procedures related to a specific **workflow** or **integration**. Examples of workflow-focused books are Document Processing or [Secure File Transfer Protocol *(SFTP)*](/legacy/legacy-experience/books/reference/sftp.md). Integration books, like Microsoft Excel or [Salesforce](/legacy/legacy-experience/books/reference/salesforce.md), connect the agent with external platforms, APIs, and services.

#### Example

For instance, the [HTTP](/legacy/legacy-experience/books/reference/http.md) book contains procedures for making HyperText Transfer Protocol *(HTTP)* requests in Kognitos. Installing the book will enable the agent [to delete a url](/legacy/legacy-experience/books/reference/http.md#to-delete-a-url), [to head a url](/legacy/legacy-experience/books/reference/http.md#to-head-a-url), [to post a payload to a url](/legacy/legacy-experience/books/reference/http.md#to-post-payload-to-a-url), etc.

        Action2["to head a url"]
        Action3["to post payload to a url"]
        Action4["to retrieve a url"]
    end
```

### Features & Benefits

Books are **modular** and **flexible**. You can add or remove them at any time, allowing agents to evolve, take on new responsibilities, and support new workflows as needed.

#### Connections

Some books require [**connections**](/legacy/legacy-experience/books/connections.md) *(such as credentials or API keys)* to interact with external platforms. Connections are secure and allow agents to interact with multiple systems seamlessly.

#### Versioning

Books are [**versioned**](/legacy/legacy-experience/books/all-books.md#versions), so your automations remain stable even as new features are introduced. Updates can enhance functionality without breaking existing workflows.

#### Many Possibilities

A single book may contain multiple actions, and when combined with other books, the agent’s skills grow exponentially. You can add various books to build powerful automation chains. For example:

> *Excel + Document Processing + Slack* → Parse invoices, update spreadsheets, and notify your team.
