 # Pure JS Buttons in Lightning
 
-JS buttons are back in Lightning! (For now, at least) And they are even more powerful than JS buttons in classic, in some respects. SOQL and DML statements supported!
+JS buttons are back in Lightning! (For now, at least) And they are even more powerful than JS buttons in classic. Run SOQL and DML statements seamlessly. Make callouts to APIs, including Salesforce APIs using named credentials directly from JavaScript! This would allow you to build buttons that do amazing things, just using JavaScript. Check out the `scripts` folder for examples. Feel free to raise a PR to contribute your own scripts.
 
 ### The Setup

 * SOQL and DML statements should be enclosed in async functions, if they are required to be contained in functions. The program automatically adds `await` to SOQL and DML statements
 * DML on Files, Attachments, Documents, etc. is not supported
 
-### For Developers: Extending to more than one Button per SObjectType
-
-If you need more than one button on an SObjectType, you may create a lightning component quickAction with the name of the custom metadata record containing your JS passed in to the `jsButton` child component. You will also need to implement an `init` method to invoke the controller method in `jsButton`. Refer to the `jsButtonQuickAction` component for implementation details
+### Using Salesforce (and other) APIs in your script
 
+You can use any of Salesforce's APIs (REST, Tooling, Metadata) by setting up a named credential for your own Salesforce instance. This allows you to write scripts for admins to perform tasks like [deleting inactive versions of flows](scripts/jsButton/deleteInactiveFlowVersions.js), or [creating new JS Buttons](scripts/jsButton/createNewJSButton.js)! You can also use named credentials to interact with other APIs as well, of course. Although, for Public APIs, you can just use `fetch` directly. The Salesforce named credential set up would need to have the following scopes (api refresh_token offline_access web). You would need to set up your own Connected App and a Salesforce Auth. Provider that uses this connected app.
