Latest README changes look good.

plugins/idea/README.md line 37:

Maybe:  

This will download gradle and the required IntelliJ dependencies...

plugins/idea/README.md line 51:

> 49: To install the plugin in your IDE, first you need to build a plugin module file (a `.zip` file), as described in the previous section.

A new file dialog will pop up: point the IDE to the zip file you have created in the step above. The IDE will require a restart - once restart is completed the installation process is completed, and the plugin is ready to be used to run and debug jtreg tests.

"...plugin jar has been obtained, it can be installed..."

Should be zip?
