+`useradd` is a low level utility that is used for adding/creating user accounts in Linux and other Unix-like operating systems.
+
+The basic synax is as follows:
+
+~~~ bash
+$ useradd [options] username
+~~~
+
+<!--more-->
+
+### Useful Options / Examples
+
+### `Basic Command - No flags`
+
+Basic Syntax:
+
+~~~ bash
+$ useradd exampleuser
+~~~
+
+This is the most basic command. The 'username' is the login name the user would log in with. Username must be unique and only one user can be added at a time. Users default home directory will be placed in the /home directory.
+
+### `Create User with Different Home Directory -d Flag`
+
+Basic Syntax:
+
+~~~ bash
+$ useradd -d [path/to/desired/directory] exampleuser
+~~~
+
+This command allows you to add a user with a different home directory than the default value of /home. The -d option is useful for certain users that are focused solely on a certain project. Their home directory could be set to the directory of their project for quick/easy access.
+
+Example:
+
+~~~ bash
+$ useradd -d data/projects/Project1 exampleuser
+~~~
+
+### `Create User in Multiple Groups -G Flag`
+
+Basic Syntax:
+
+~~~ bash
+$ useradd -G [Group List, comment delimited] exampleuser
+~~~
+
+-G command allows user to be added to specific groups upon account creation. This would be userful when creating a new Admin account. Instead of manually adding user to teach group, user could be added to the groups during creation
+Example:
+
+~~~ bash
+$ useradd -G admins,webadmins exampleuser
+~~~
+
+### `Create User with Account Expiration Date -e flag`
+
+Basic Syntax : 
+
+~~~ bash
+$ useradd -e [Date YYYY-MM-DD Format] exampleuser
+~~~
+
+The new user will only be able to login for a limited amount of time. This flag would be ideal for any seasonal or third party workers that need access to system for a limited amount of time.
+
+Example: 
+
+~~~ bash
+$ useradd -e 2018-10-31 exampleuser
+~~~
+
+### `Create User with Custom Comments -c flag`
+Basic Syntax:
+
+~~~ bash
+$ useradd -c <"Comments"> exampleuser
+~~~
+
+This option would be useful if you wanted to add additional information about the newly created user such as name, phone number or email.
+
+Example:
+
+~~~ bash
+$ useradd -c "Example User 123-456-7890" exampleuser
+~~~
