 - Use the search tool to create some test cases. Enter your search and click the "Add Testcase" button to convert the results in a testcase. Tweak, tag, and edit them in the test cases screen.
 - Run and explore metrics for your test cases from the metrics screen. 
 - Export your configuration and testcases and use them on the command line using [rankquest-cli](https://github.com/jillesvangurp/rankquest-cli).
-- Use any of the built in search plugins, or add your own javascript function in the UI.

+To get results from your search API, you need to use a search plugin. A search plugin fetches results and picks 
+the response apart to extract the id and a label for each search result. Note. as this runs in a browser, your search API 
+must set the appropriate CORS headers.

+Rankquest Studio comes with four plugins. Three
 of those are provided by rankquest-core and are written in Kotlin:
 
 - JsonGetAPIPlugin - allows you to do an HTTP GET against any API that returns Json
 - JsonPostAPIPlugin - allows you to do an HTTP POST against any API that returns Json
 - ElasticsearchPlugin - lets you query Elasticsearch

+A fourth plugin is bundled with Rankquest Studio and allows you to **run javascript in your browser**. Note. while this works great inside the browser, this plugin does not work outside the browser and cannot be used with rankquest-cli. Using Javascript,
 you can use the browser fetch API to access your server.
 
 Finally, you can of course create your own plugin in Kotlin. However, this is a bit more involved and you will have to modify

 so that it can use your plugin. For this, refer to the source code and the existing plugins.
 
+An **alternative to writing your own plugin may also be proxying** your search API such that you can use one of the builtin
+plugins. This may be easier than customizing the UI for your plugin and is something you can do with a few lines of code in your preferred programming language.

 ## Why another tool?
