+
+## How to use this app
+Program will automatically create 3 folders `input`, `encrypt`, `output`.
+After starting you can put files inside folders, for encryption put files in `input` folder and encrypted file will pop up in
+`encrypt` folder, for decryption put files ex. `fileExtension-xOrƎ-fileName.XORe` in `encrypt` folder and 
+decrypted file will pop up in `output` folder.
+
+All encryption and decryption processes requiring encryption key word which you can enter or use file `key.properties`,
+program will also ask you if you want to save key word in to a file.
+
+For all functions to work correctly you will need a key word that can be stored in `key.properties` file or manually on piece of paper.
 
 ## What is XOR
 XOR is one of the best encryption that use special key word. The XOR encryption algorithm is an example of symmetric encryption where the same key is used to both encrypt and decrypt a message.
