We have added a new template, a Software Architecture Document template, to Docstell. It is based on arc42’s architecture documentation. This gives you a really good starting point for your documentation and we think that using this together with the Docstell functionality is a really good match. You find more information about arc42 over at their website, https://arc42.org.
You will find this template in the Docstell Template Gallery. We added one with the basic structure and one with all the help texts that explain what goes in each section.
