FAQ

1. If I exit the bot using anything other than bye, will I lose data?

No, data might not be lost. However, there is a chance of data corruption which may inevitably result in a full or partial loss of data depending on where it occurs.

2. How do I transfer data to other machines?

Copy the ip.jar file and saveFile.txt to the other machine. Place both of the files in the same directory, and Jarvas will be able to load the data file.
