If I have a plugin that I want to deploy from the DevExpress CodeRush Community site, how do I deploy it onto my machine?
How do I install a plugin
Instructions are linked to, from the top of each plugin page. Look for the blue button that says "Install help" (Also linked here)
Essentially all you have to do is drop the dll in the right directory and restart studio.
Issues
One potential issue surrounds the idea that dlls built on machines other than your own, are not inherently trusted by your machine and therefore will not always be loaded until they have been unblocked. (A one time exercise per dll at most)
Travis Illig has some information on how to deal with this situation.
