 Try to run `goodbyedpi.exe` without any arguments first. If you can open blocked websites it means your ISP has DPI which can be circumvented. This is the slowest mode.
 
-Then try `goodbyedpi.exe -2`. It should be faster for HTTPS sites.
+Then try `goodbyedpi.exe -2`. It should be faster for HTTPS sites. Mode `-3` speed ups HTTP websites.
 
-Use `goodbyedpi.exe -3` if it works for your ISP's DPI. This is the fastest mode but not compatible with every DPI.
+Use `goodbyedpi.exe -4` if it works for your ISP's DPI. This is the fastest mode but not compatible with every DPI.
