Good but requires expert install

Great plugin. I’m evaluating it now as a backend Redis cache. However, installation was not straightforward or clear. I wish it was automatic. However, the manual install requires copying a file manually. If you run multiple WordPress sites on a self-hosted install, you must also make sure to edit the object-cache.php file and add a cache salt key or you will get errors. Once these are resolved, it seems to be functioning well.

4 stars for the excellent plugin.
-1 for the difficult installation. I wish it were more straightforward.
