The file "downloads" has minimal changes apart from formatting of the code includes. Here are the issues identified:

1. When including source code in the asciidoc section using the "include" directive, ensure consistent formatting in the attributes used. In the updated version, the render and indent attributes have been removed, which is incorrect usage. Make sure this aligns with the necessary requirements for rendering code snippets using include directives.

2. Additionally, there are minor sections where consistent naming conventions and terms should be double-checked to align with the project's conventions (though not directly applicable to a specific modified line in this update).

Apart from these, the provided text remains structurally and contextually correct per the guidelines specified for technical documentation.
