You can easily add a hyperlink from your Mathematica source file to a notebook document. This might help you to document the implementation of your work.
Any comment that contains the name of a notebook can work as a hyperlink. The links can be relative to the root of the project by starting with a slash '/' or be relative to the source file. Furthermore, you can link to a particular cell if you append the CellID to the name.
To activate the link you should hold down the Ctrl key and move the
mouse over the name. It should change appearance to that of a hyperlink,
as shown below.
When you click on the link, the notebook front end will open that notebook document with the relevant cell selected.
