+== Add data
 
-To start working with your data in {kib}, use one of the many ingest options,
-available from the home page.
-You can collect data from an app or service,
-or upload a file that contains your data.  If you're not ready to use your own data,
-add a sample data set and give {kib} a test drive.
+The best way to add data to the Elastic Stack is to use one of our many integrations,
+which are pre-packaged assets that are available for a wide array of popular
+services and platforms. With integrations, you can add monitoring for logs and
+metrics, protect systems from security threats, and more.
+
+All integrations are available in a single view, and
+{kib} guides you there from the *Welcome* screen, home page, and main menu.

-=== Add data
+=== Add data with Elastic solutions
 
-Want to ingest logs, metrics, security, or application data?
-Install and configure a Beats data shipper or other module to periodically collect the data
-and send it to {es}. You can then use the pre-built dashboards to explore and analyze the data.
+A good place to start is with one of our Elastic solutions, which
+offer experiences for common use cases.
+
+* *Web site search crawler.*
+Discover, extract, and index your web content into App Search engines using the
+{app-search-ref}/web-crawler.html[Enterprise Search web site crawler].
+Search across Google Drive, GitHub, Salesforce, and many other web services using
+{workplace-search-ref}/workplace-search-content-sources.html[Workplace Search content sources].
+
+* *Elastic APM.*
+Get logs, metrics, traces, and uptime data into the Elastic Stack.
+Integrations are available for popular services and platforms,
+such as Nginx, AWS, and MongoDB,
+and generic input types like log files.
+Refer to {observability-guide}/observability-introduction.html[Elastic Observability]
+for more information.
+
+* *Endpoint Security.*
+Protect your hosts and send logs, metrics, and endpoint security data
+to Elastic Security.
+Refer to {security-guide}/ingest-data.html[Ingest data to Elastic Security]
+for more information.
+
+[float]
+=== Add data with programming languages
+
+Add any data to the Elastic Stack using a programming language,
+such as JavaScript, Java, Python, and Ruby.
+Details for each programming language library that Elastic provides are in the
+https://www.elastic.co/guide/en/elasticsearch/client/index.html[{es} Client documentation].
+
+If you are running {kib} on our hosted {es} Service,
+click *View deployment details* on the *Integrations* view
+to verify your {es} endpoint and Cloud ID, and create API keys for integestion.
+
+[float]
+=== Add sample data
+
+Sample data sets come with sample visualizations, dashboards, and more to help you
+explore {kib} before you add your own data.
+In the *Integrations* view, search for *Sample Data*, and then add the type of
+data you want.

-=== Add Elastic Agent
-
-*Elastic Agent* is the next generation of
-data integration modules, offering
-a centralized way to set up your integrations.
-
-With *Fleet*, you can add
-and manage integrations for popular services and platforms, providing
-an easy way to collect your data, and manage {elastic-agent} installations in standalone or {fleet} mode. The integrations
-ship with dashboards and visualizations,
-so you can quickly get insights into your data, and {fleet} mode offers several advantages:
-
-* A central place to configure and monitor your {agents}.
-
-* An overview of the data ingest in your {es} cluster.
-
-* Multiple integrations to collect and transform data.

+In the *Integrations* view, search for *Upload a file*, and then drop your file on the target.
