+***Backup is the best promise to data.***
+
+After losing all files from stepping into the campus of university late last year, I finally realized this. Watching all my works and memories become zero bytes but not being able to do anything about it is catching up with me, and that's why I set out to begin this program. The program's name *Promissum*, the origin of *Promise* from Latin, means the program should possess the ability to backup important files well, and the followings are what Lekco Promissum can do:
+
++ Backups specified directories and theirs files to other specified directories.
++ Provides multiple compare modes to update files.
++ Provides plans to execute backup tasks automatically by given settings.
++ Provides choices to cope with files need deleting, such as moving them into a specified folder, marking them with versions, clearing out-dated files periodically and so on.
++ Allows users to set up rules to exclude files that don't need to backup.
++ Records all actions Lekco Promissum does to the files, and be able to output them into Excel documents.
+
+Hope you find Lekco Promissum helpful and submit issues if possible.
+
+***Make data immortal.***
