* Make a copy of your current workflow
* make a screen to be used in your transition and include description field and any others you might want users to consider updating. I highly recommend requiring Resolution. 
* Edit the copied workflow in Inactive section under admin>issues>workflows
* click on the transition desired and add the new screen
* add a Validator to the transition for field updated and choose descriptions. Choose to add error message. Repeat for Resolution if you chose to do so.
* go back to your project setting > workflows and add workflow and locate the copied/edited one. 
* associate all issue types desired for that project to this workflow. 
* publish
