+You have many options for ingesting data into your {es} project on {serverless-full}.
 
 The best ingest option(s) for your use case depends on whether you are indexing general content or time series (timestamped) data.
 
-**General content**
+// Use APIs
 
-General content includes HTML pages, catalogs, files, and other content that does not update continuously.
-This data can be updated, but the value of the content remains relatively constant over time.
-Use connector clients to sync data from a range of popular data sources to {es}.
-You can also send data directly to {es} from your application using the API.

+== Ingest data using APIs
+
+You can use the <<elasticsearch-http-apis,{es} REST APIs>> to add data to your {es} indices, using any HTTP client, including the <<elasticsearch-clients,{es} client libraries>>.
+
+While the {es} APIs can be used for any data type, Elastic provides specialized tools that optimize ingestion for specific use cases.

+== Ingest general content
+
+General content is typically text-heavy data that does not have a timestamp.
+This could be data like knowledge bases, website content, product catalogs, and more.
+
+You can use these specialized tools to add general content to {es} indices:

-**Times series (timestamped) data**
+== Ingest time series data
 
 Time series, or timestamped data, describes data that changes frequently and "flows" over time, such as stock quotes, system metrics, and network traffic data.
-Use {beats} or {ls} to collect time series data.
+
+You can use these specialized tools for adding timestamped data to {es} data streams:
