+* Step 1: check if main group exists
+* Step 2: Add user to user_list.txt
+
+Example:
+
+```txt
+# 2022-12-12
+1;test.foo;group-a;allow
+```
+
+* Step 3: run create script in root/users `bin/create_user.sh`
+
+Not, if unsure use `-t` for testing or `-i` for info only.
+
+Example output for `-i`:
+
+```sh
+$> bin/create_user.sh -i
+User: 'test.foo:group-a();sshallow', SSH: hostname.com#grou-a#test.foo#ed25519.pem
+```
+
+Run output (example):
+
+```sh

+! Override password set
+ > Create ssh key-pair '/root/users/bin/../ssh-keygen/hostname.com#group-a#test.foo#ed25519.pem'

+```
+
+* Step 5: Download ZIP file to local computer and extract
+
+Overwrite user_list.txt file if it exists
+
+In the zup file there are the following files:
+
+* user_password.YYYYMMDD-HHmmss.txt (creation timestamp)
+* ssh-keygen/hostname#group#user#keytype.pem
+* ssh-keygen/hostname#group#user#keytype.pem.pub
+
+The .pem key has to be given to the user, the pub key is for reference only
+
+* Step 6: test login
+
+In the folder where the data was extracted
+
+```sh
+ssh -i ssh-keygen/hostname#group#user#keytype.pem user@hostname
+```
+
+Hand over to the user:
+
+* username
+* hostname
+* PEM key file
+* PEM key password
+
+If the password needs to be removed:
+
+```sh
+ssh-keygen -p -f ssh-keygen/hostname#group#user#keytype.pem -P <old password> -N ""
+```
