+# ### Adjusting the mkdocs theme
+
+# `semiliterate` also makes it possible to add generated files to the mkdocs
+# theme. It does this by detecting if a `theme.custom_dir` parameter has been
+# set in the mkdocs configuration, and if so, it adds the corresponding
+# directory in the generated docs dir to the theme search path. (Note this
+# means that
+# files in the corresponding subdirectory of your project will be copied into
+# the resulting doc site unless their names start with a '.')
+# end-md
