+## Users
+
+Check users by looking at `/etc/passwd`  
+
+### Add users
+Basic usage:  
+`# useradd -m (user)`  
+
+Important options:  
+```
+login name -> by default
+group -> -G //separate multiple by commas: group1,group2
+with home dir -> -m
+shell -> -s
+full name -> -c
+```
+
+Example more complicated usage:  
+`# useradd -m -c "Bruno Huber" -s /bin/bash -G buchhaltung,sudo bruhub`  
+
+### Add user to groups
+Add user to more groups:  
+`# usermod -a -G (group1),(group2) (user)`  
+
+Alternative command:  
+`# gpasswd -a (user) (group)`  
+
+### Remove user from group
+`# gpasswd -d (user) (group)`  
+
+## Groups
+Check a user's groups with `id (user)`  
+
+### Create group
+`# groupadd (group)`  
+
+### Rename group
+`# groupmod -n (new_group) (old_group)`  
+
+### Delete group
+`# groupdel (group)`
