 # VBAChromeDevProtocol
 VBA (Excel) based wrapper for Chrome Developer Protocol (CDP) - sorta a VBA version of Puppeteer/Selenium
+
+Note: if you can use Puppeteer, Playright, Selenium, or some other tool - then use it!
+But if you can only use VBA, then this is meant to provide a means to automate Chrome or Edge based browsers.  (Possibly Firefox via its limited CDP support, though currently untested/nonfunctional). 
+
+TODO: this currently relies on Chrome/Edge's ability to do the CDP via pipes when started, a future version will connect to the websocket to allow connecting to existing browsers.
+
+See https://chromedevtools.github.io/devtools-protocol/ for overview of Chrome Devloper Protocol
