+List of vote levels used to customize comment appearance based on score.
+Provide a comma-separated values (eg. `"0,5,10,25,100"`) or a JSON array (eg. `"[-5,5,15]"`).
+
+For example, the value `"-5,5"` will cause each `isso-comment` to be given one of these 3 classes:
+
+- `isso-vote-level-0` for scores lower than `-5`
+- `isso-vote-level-1` for scores between `-5` and `4`
+- `isso-vote-level-2` for scores of `5` and greater
+
+These classes can then be used to customize the appearance of comments (eg. put a star on popular comments)
