The "Blanco Manual" is an Adobe FrameMaker 2020 template.
It is an A5 template meant for software documentation, but it will fit perfectly to most sorts of documentation/instructions, actually.
It has been made with options for multi-volume publishing, with a a header which enables volumes with different colour coding.
We have supplied the template with MIF files, making it possible for you to open the template in earlier versions of FrameMaker too.
