 ## Configuration
 
-The `applicationConfig` plugin provides read and write APIs that allow OpenSearch Dashboards users to manage dynamic configurations as key-value pairs in an index. The `cspHandler` plugin registers a pre-response handler to `HttpServiceSetup`, which gets `frame-ancestors` value from the dependent `applicationConfig` plugin and then rewrites to the CSP header. Enable both plugins within your `opensearch_dashboards.yml` file to use this feature. The configuration is shown in the following example. Refer to the `cspHandler` plugin [README](https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/src/plugins/csp_handler/README.md) for configuration details.

 ## Enable site embedding for OpenSearch Dashboards
 
-To enable site embedding for OpenSearch Dashboards, update the directive `frame-ancestors` in the CSP rules using CURL. When using CURL commands with single quotation marks inside the `data-raw` parameter, escape them with a backslash (`\`). For example, use `'\''` to represent `'`. The configuration is shown in the following example. Refer to the `applicationConfig` plugin [README](https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/src/plugins/application_config/README.md) for configuration details.
