 ## Troubleshooting
 
+### AssetBundle was not built
+
+When building and uploading, this error message may appear. It's caused by VRCSDK building an AssetBundle whose filename has mixed caps, when Unity AssetBundles are really only supposed to have lowercase filenames.
+
+The solution is to import this unitypackage: https://github.com/thegu5/VRCSDKonLinux/releases
+
+Importing this will mod the appropriate VRCSDK methods to be case-sensitive-aware.
