 For developers:
 
-The zip should work out pretty much out of the box. You may need to update the unity and c# library references for the FNPlugin and OpenResourceSystem solutions. And maybe your output paths. All assets for the plugin are included as linked references from the addon folders in the project, so they shouldn't copy. You may want to copy my gitignore to your repo as well.
