+## Browser Compatibility
+
+### Safari - Not compatible
+Safari doesn't like the way SwiftSplit communicates with LiveSplit One, so LiveSplit stalls when trying to connect.
+
+### Firefox - Mostly compatible
+If you only have one display, Firefox will slow down the LiveSplit One tab, causing it to record incorrect times.
+If you keep the LiveSplit window open on a second display this isn't an issue.
+
+### Chrome - Compatible
+Chrome doesn't seem to have the same optimization as Firefox, which in this case is a good thing. If you're using 
+Firefox and your splits are coming out wrong, try with Chrome and see if that fixes it.

 # Route JSON
 Routes are configured using a JSON file and use "events" generated by SwiftSplit. They consist of a reset event and a
