+# Content connectors
+
+Elastic's content connectors allow you to extract, transform, index, and sync data from third-party applications including Github, PagerDuty, Jira, OpsGenie, Teams, Google Drive, Slack, email, and more. To see a complete list of the available connectors, follow the setup instructions below. 
+
+## Setup 
+{{stack}} supports two deployment methods: Elastic managed, and self-managed. {{serverless}} only supports Elastic managed deployments. Self-managed deployments require you to manage the {{elastic-agent}} that forwards data to Elastic and allow you to customize the connector's code, whereas Elastic managed deployments use agentless technology and do not allow customization.
+
+To learn about set up for self-managed connectors, refer to [Self managed connectors](elasticsearch://reference/search-connectors/self-managed-connectors.md). To set up an Elastic managed connector:
+
+- Use the [global search field](/explore-analyze/find-and-organize/find-apps-and-objects.md) to find "Content conectors".
+- Click **New Connector**.
+- Under **Connector**, select your desired data source.
+- Under **Setup**, select your deployment method. 
+- Under **Configure index & API key**, click **Generate configuration**. After a few seconds, this will create a new connector and a new index for its data, and display their names and IDs. You can click their names to view details about each. 
+- Click **Next** to continue to the **Configuration** page. This is where you can select details related to your specific data source. For more information about configuring your selected data source, follow the link on the left to the **Connector reference**.
+- When configuration is complete, click **Next**. The **Finish up** page appears. Here you can set up recurring connector syncs, run a manual sync, or use queries and dev tools to interact with your data. Each sync updates the data in the connector's {{es}} index. You can also manage the connector.
+
+
+## Manage a connector 
+
+To manage an existing connector:
+
+- Use the [global search field](/explore-analyze/find-and-organize/find-apps-and-objects.md) to find "Content connectors". 
+- Click the connector you want to manage to open its settings page, which has six tabs:
+  - **Overview**: View general information such as the connector's name, ID, status, pipeline, and content sync history. Manage the connector's pipeline and attached index.
+  - **Documents**: View data from the connector.
+  - **Mappings**: Update index mappings for the connector's data.
+  - **Sync rules**: Use EQL to select which documents from the connector you wish to save. By default, all documents are saved.
+  - **Scheduling**: Define when data from this connector gets synced, and set up document level security. A `Full content sync` deletes existing data in your index before fetching from your data source again. An `Incremental content sync` fetches updated data only, without deleting existing data. 
+  - **Configuration**: Edit the connector's data source-specific configuration.
