 # Splitted Secret
 The purpose of this software is to splitt a secret over multiple people. Just if a defined amount of this people meet together they can encrypt the secret and have access to it. 
 
-# testing
-```bash 
-python scripts/main.py --mode cleanup && 
-echo "werewrw" > data/decrypted/main_data/test123.txt
-echo "werewrw" > data/decrypted/main_data/test124.txt
-mkdir data/decrypted/main_data/folder
-echo "werewrw" > data/decrypted/main_data/folder/test124.txt

+Before executing the script it may be necessary to install the following software packages:
+
+```bash
+pacman -S gpg tar python pip python-pip
+pip install numpy
 ```
-# Requirements to know
-- Amount of People
-- How much people need to reunite for decrypting
+## commands
 
-# Requirements to implement
-- Plattform independend
-- easy to use
+## cleanup data
+
+### delete all data
+
+To delete all data execute:
 
-# required software
 ```bash 
-    pip install numpy
-    gpg
-    ecryptfs-utils 
-    ecryptfs-simple
-    python
-    pip
+python scripts/main.py --mode cleanup

+### delete decrypted data
+To delete all encrypted data execute:
+
+```bash 
+python scripts/main.py --mode cleanup --file-types decrypted
+```
+
+### delete all encrypted data
+To delete all encrypted data execute:
+
+```bash

+
+## decrypt
+
+### decrypt automatic (todo)
+To decrypt the data for a defined user type in:
+
+```bash

+```
+
+### decrypt defined user
+To decrypt the data for a defined user type in:
+
+```bash 
+python scripts/main.py --mode decrypt --user "<<user_id>>"
+```
+
+## encrypt
+
+### encrypt all data
+
+```bash
