+# User Management
+The root user (also known as the superuser or su) can access any file, make system changes, and lots of room for security vulnerabilities.
+For this reason you should aspire to run services as a non-root user.
+
+### Create a non-root user
+`useradd USERNAME`
+
+Where username can be anything, but should reflect the service/jail's name for diagnostic.
+
+Then a password should be created as some commands require a non-blank password to be inserted:
+`passwd USERNAME`
+
+If you want the ability to run commands as root, add the user to the sudo group
+`usermod -aG sudo USERNAME`
+
+This WILL require a non-blank password, and any command run with sudo will be run as root not as the user. But it saves time compared to switching users to root to install/change things then switching back.
+
+### Switch to user
+`su -l USERNAME`
+
+### Put a password on Root
+While logged in as root run `passwd`
+
+# Common tweaks
+### Update repository list 
+`sudo apt update`
+
+### Install common services 
+`sudo apt install nano wget curl git`
+
+### Set Static IP
+See `Networking`
+
+### Install Docker
+```
+apt install curl && cd /tmp && curl -fsSL https://get.docker.com -o get-docker.sh && sudo sh get-docker.sh && cd ~ && docker
+```
