+App doesn't track Systems visited
+--
+When you have the "Automatically make a log entry on entering a system" option selected, EDMC uses Elite: Dangerous' logs to track and display the systems that you visit, and to display the current system. Some people find that this doesn't work. The problem is most likely due to EDMC using the logs from a different copy of Elite: Dangerous than the copy that you're running.
+
+When looking for the log files, EDMC assumes:
+- That you're running "Horizons" 64bit, if you have both Horizons and Season 1 installed.
+- That you're running from Steam, if you have both Steam and non-Steam versions installed.
