Kyatric: Thanks I got it installed. It wouldn't install at first as the browser console was showing the error "Error installing addon: Error: missing addon.json" The addon.json file was there but it was 2 folders deep so I went to that folder re-zipped the files and was able to load it.
So if anyone has trouble adding this addon, do this:
1. Unzip the downloaded zip file
2. go to where the addon.json file is and zip all of those files/directories.
3. Save zip file with the name Kyatric mentioned above: "cbhash_release_r70_1.0-c3.c3addon"
After that you should be able to add it via the addon manager in C3
Thanks again Kyatric!
