For now, our process does not do anything: let us add technosphere exchanges so that our process produces something. In order to add a product produced by the process, inside the curly braces after the process keyword, add another block (a keyword followed by braces, to define something) with the products keyword:

process my_first_process {
    products {
        1 kg bread

By convention, we indent lines inside blocks (press Tab to move a line to the right).

Bravo! you have described a process that produces 1 kg of bread (in the technosphere).
