Copy the Content folder from the latest release and edit the staticwiki.ini file to change your wiki file.
Then, start the StaticWikiHelper app, and open the folder you created. You should open the folder that contains the staticwiki.ini file, not a sub-folder.
From then on, while StaticWikiHelper is open, it will constantly generate your HTML files in the output folder (staticwiki by default) by reading the .md files in your source folder (pagesources by default)
based on the theme file (staticwikitheme/theme.html by default).
Finally, the Navigation.list file (located in the same directory as staticwiki.ini) can be used to customize the page navigation of your wiki.
You can create links one line at a time in a form of Name=URL per line. An example would be something like Google=http://www.google.com.
