# Document conventions
<a name="docconventions"></a>

The following are common typographical conventions for the *Amazon Systems Manager User Guide*. 

**Differentiated examples for local operating systems or command line languages**  
We use tabs to present different examples of commands based on a user's local operating system type. For Linux and macOS examples, we use the backslash (`\` ) character to break long commands into multiple lines. For Windows Server examples, we use the caret (`^`) character to break commands into multiple lines.  
Example:  

```
aws ssm update-service-setting \
    --setting-id arn:aws-cn:ssm:region:aws-account-id:servicesetting/ssm/managed-instance/activation-tier \
    --setting-value advanced
```

```
aws ssm update-service-setting ^
    --setting-id arn:aws-cn:ssm:region:aws-account-id:servicesetting/ssm/managed-instance/activation-tier ^
    --setting-value advanced
```

**Elements in the user interface**  
Formatting: Text in bold  
Example: Choose **File**, **Properties**.

**User input (text that a user types)**  
Formatting: Text in a monospace font  
Example: For the name, type **my-new-resource**.

**Placeholder text for a required value**  
Formatting: Text in *italics*  
Example:  

```
aws ec2 register-image --image-location amzn-s3-demo-bucket/image.manifest.xml
```
