The use of the Parameters section in Azure Resource Manager (ARM) templates is vital for documenting deployment values that are reused throughout the template. This section allows you to define input parameters that can be set at deployment time, which makes the template more flexible and reusable.

By utilizing the Parameters section, you can specify values such as the names of resources, sizes, and other settings that might change depending on the environment (e.g., development, testing, production). This not only promotes clarity and understanding of what values are intended for configuration but also enhances the maintainability of the template. Anyone deploying the solution can easily see the configurable values, making it straightforward to adapt the deployment for different scenarios without needing to change the core template structure.

In contrast, the Outputs section is primarily used for returning values from a deployed template and does not directly contribute to the documentation of input parameters for reuse. The Variables section is meant for defining non-user defined values that can be reused within the template logic itself, but it is not ideal for documenting deployment values intended for external input. The Resources section lists the resources being deployed and is not meant for documenting or specifying parameters. This makes the Parameters section the optimal choice for documenting and configuring reusable deployment values in Azure templates.
