Write-protect documentation for self-written Add-on package

Question

My package works fine so far, and now I want to add some documentation. I have put a file in

FileNameJoin[{ $UserBaseDirectory, "Applications", "myPkg", "Documentation", "English", "Guides", "TableOfContents.nb"}].

The content of the notebook is:

    Notebook[{Cell["Table of Contents for pkgTools", "TOCDocumentTitle", 
       ShowGroupOpener -> False, TextAlignment -> Center], Cell[TextData[
        ButtonBox["Tutorial: CodingStandards", Rule[BaseStyle, "Link"], 
          Rule[ButtonData, "paclet:pkgTools/tutorial/CodingStandards"]]], 
       "TOCChapter", ShowGroupOpener -> True], Cell[TextData[
        ButtonBox["Tutorial: CreateNewApplication", Rule[BaseStyle, "Link"], 
          Rule[ButtonData, "paclet:pkgTools/tutorial/CreateNewApplication"]]], 
       "TOCChapter", ShowGroupOpener -> True], Cell[TextData[
        ButtonBox["Tutorial: ToDoList", Rule[BaseStyle, "Link"], 
          Rule[ButtonData, "paclet:pkgTools/tutorial/ToDoList"]]], "TOCChapter", 
       ShowGroupOpener -> True]}, StyleDefinitions -> 
      FrontEnd`FileName[{"Wolfram"}, "Reference.nb"]]

Now when I load the package, it appears in the Function navigator under "Add-Ons". When I click on it, the notebook opens. But it gets immediately the "modified" Tag, which is confusing to users of the package who just want to read the documentation.

Is there a way to write-protect the documentation notebook?

Answer 1

As @Szabolcs mentioned, the standard way to write-protect a notebook is to set the option Saveable -> False when creating the notebook.

Needless to say: if you want to write fully professional documentation, Wolfram Workbench $\;$ is your best solution. It automatically creates write-protected documentation.
