Be sure that you have completed the installation of the SitecoreUML Service for Sitecore before proceeding with this step.
The latest version of the SitecoreUML Service for Sitecore includes a new Documentation Configuration item, found at /sitecore/system/Modules/SitecoreUML/Documentation Configuration (by default; you can change this in the SitecoreUML.config), that controls some of the options for how your documentation should be generated. Note that while setting up the Documentation Configuration item is optional, if you do not configure the item then none of the Helix Diagrams will be generated, but note that the item does not need to be published, unless your SitecoreUML Service for Sitecore is configured to retrieve data from the web database.
Each of the following steps is optional, but recommended:
Provide a title for your documentation, by specifying it in the
Documentation Title field.
For each layer, specify the root template folder item in the
[Foundation|Feature|Project] Layer Root field.
For each layer, select the module folders that belong to the layer in the
[Foundation|Feature|Project] Module Folders field.
Note that module folders are not selected by the system, by default, so if do not select any module folders than no modules will appear in your layers and Helix Diagrams will not be generated for the modules
Note that you may choose to select module group folders as module folders or you may select the individual modules within those module group folders. However, at this time identifying a module as belonging to a module group is not currently supported.
SitecoreDXG needs to know the module folders in order to be able to generate the Helix Diagrams. Unfortunately, there is no reliable way to identify module folders, due to the fact that some modules live within module groups.
When the first version of the Helix Diagram features were initially created, they were developed for SitecoreUML and used Regular Expressions in order to determine which paths belonged to module folders. Despite being made user-configurable, this approach proved unreliable for varying architectures, and tedious for users to update. As such, the Regular Expression approach was abandoned for the implementation in SitecoreDXG and replaced with fields for selecting the modules that belong to each layer.
It is worth mentioning that while the Documentation Configuration item is included in the SitecoreUML Service for Sitecore, it is currently only used by SitecoreDXG. There are currently plans in place to rewrite the SitecoreUML Service for Sitecore to be a part of SitecoreDXG and to update SitecoreUML to call SitecoreDXG for reverse engineering and deployment needs.
