After recently releasing V0.2.10, we're now hard at work with a new version that will have some fairly significant changes for the user's experience when rendering. These changes are best described by a video, so be sure to check that out as its linked in this article :)
A more in depth discussion on the changes and why they are considered a big improvement on the current way you render using our addon are in this article on our website.
The gist is that you pretty much render with Crowdrender exactly the same way you render with cycles or eevee. Just make the appropriate choice of which of the available engines you want to use and then use F12 or the render menu controls as normal. See the video for a demo, and read the article for more info :)
