Summary:
The documentation page demonstrates a Windows bias in the certificate generation section, where only Windows-specific instructions and PowerShell commands are provided for using the step CLI. There are no equivalent Linux or macOS command-line examples, and the instructions reference opening a Command Prompt and using Windows environment variables. The .NET code sample also assumes usage in Visual Studio, a Windows-centric IDE, without mentioning cross-platform alternatives.
Recommendations:
- Provide explicit Linux and macOS command-line examples for generating certificates with the step CLI, including terminal commands and file paths.
- Avoid referencing Windows-specific actions (e.g., 'Win+R type %USERPROFILE%') without cross-platform equivalents; instead, mention generic terminal navigation or provide alternatives for different OSes.
- Include instructions for running the .NET sample on Linux/macOS (e.g., using VS Code, JetBrains Rider, or the dotnet CLI) and clarify that the code is cross-platform.
- Where file paths are referenced, use cross-platform path examples or note the differences.
- If referencing IDEs or tools, mention cross-platform options and not just Visual Studio.

Flagged Code Snippets
## Publish and subscribe to MQTT messages
The following sample code is a simple .NET publisher that attempts to connect and publish to a namespace and subscribes to the MQTT topic. You can modify the code for your requirements and run it in Visual Studio or another design tool.
You need to install the MQTTnet package (version 4.1.4.563) from NuGet to run this code. In Visual Studio, right-click the project name in Solution Explorer, go to **Manage NuGet packages**, and search for **MQTTnet**. Select **MQTTnet package** and install.

> [!IMPORTANT]
> Update the client certificate and key pem file paths depending on the location of your client certificate files. Also, ensure that the client authentication name and topic information match with your configuration.
