 It is perfectly normal for a package to only have files in the "opt"

-6. Debugging scripts					*debug-scripts*
+6. Creating Vim packages				*package-create*
+
+This assumes you write one or more plugins that you distribute as a package.
+
+If you have two unrelated plugins you would use two packages, so that Vim
+users can chose what they include or not.  Or you can decide to use one
+package with optional plugins, and tell the user to add the ones he wants with
+`:packadd`.
+
+Decide how you want to distribute the package.  You can create an archive or
+you could use a repository.  An archive can be used by more users, but is a
+bit harder to update to a new version.  A repository can usually be kept
+up-to-date easily, but it requires a program like "git" to be available.
+You can do both, github can automatically create an archive for a release.
+
+Your directory layout would be like this:
+   start/foobar/plugin/foo.vim    	" always loaded, defines commands
+   start/foobar/plugin/bar.vim    	" always loaded, defines commands
+   start/foobar/autoload/foo.vim  	" loaded when foo command used
+   start/foobar/doc/foo.txt       	" help for foo.vim
+   start/foobar/doc/tags          	" help tags
+   opt/fooextra/plugin/extra.vim  	" optional plugin, defines commands
+   opt/fooextra/autoload/extra.vim  	" loaded when extra command used
+   opt/fooextra/doc/extra.txt  	        " help for extra.vim
+   opt/fooextra/doc/tags  	        " help tags
+
+This allows for the user to do: >
+	mkdir ~/.vim/pack/myfoobar
+	cd ~/.vim/pack/myfoobar
+	git clone https://github.com/you/foobar.git
+
+Here "myfoobar" is a name that the user can choose, the only condition is that
+it differs from other packages.
+
+In your documentation you explain what the plugins do, and tell the user how
+to load the optional plugin: >
+	:packadd! fooextra
+
+You could add this packadd command in one of your plugins, to be executed when
+the optional plugin is needed.
+
+Run the `:helptags` command to generate the doc/tags file.  Including this
+generated file in the package means that the user can drop the package in his
+pack directory and the help command works right away.  Don't forget to re-run
+the command after changing the plugin help: >
+	:helptags path/start/foobar/doc
+	:helptags path/opt/fooextra/doc
