 Installation & usage ~
 
-Unzip the most recent ZIP archive [3] file inside your Vim profile directory
-(usually this is '~/.vim' on UNIX and '%USERPROFILE%\vimfiles' on Windows),
-restart Vim and execute the command ':helptags ~/.vim/doc' (use ':helptags
-~\vimfiles\doc' instead on Windows). As an example we'll publish the plug-in
-using itself. First create a tags file that contains entries for the files you
-want to publish using a shell command such as:
->
-    $ ctags -Rf ~/.publish_tags ~/.vim/
+_Please note that the vim-publish plug-in requires my vim-misc plug-in which is
+separately distributed._
+
+Unzip the most recent ZIP archives of the vim-publish [3] and vim-misc [4]
+plug-ins inside your Vim profile directory (usually this is '~/.vim' on UNIX
+and '%USERPROFILE%\vimfiles' on Windows), restart Vim and execute the command
+':helptags ~/.vim/doc' (use ':helptags ~\vimfiles\doc' instead on Windows). If
+you prefer you can also use Pathogen [5], Vundle [6] or a similar tool to
+install & update the vim-publish [7] and vim-misc [8] plug-ins using a local
+clone of the git repository.
 
+As an example we'll publish the plug-in using itself. First create a tags file
+that contains entries for the files you want to publish using a shell command
+such as:
+>
+  $ ctags -Rf ~/.publish_tags ~/.vim/
+<
 If this doesn't work because |ctags| isn't installed you can download it from
 the Exuberant Ctags homepage [1], or if you're running Debian/Ubuntu you can
 install it by executing the following shell command:
 >
-    $ sudo apt-get install exuberant-ctags
-
+  $ sudo apt-get install exuberant-ctags
+<
 The plug-in needs an up-to-date tags file so that it can create hyperlinks
 between the published files. Now start Vim and write a script that registers
 the tags file you just created and calls the function 'Publish()' as follows:
 >
-    :set tags=~/.publish_tags
-    :let sources = '/home/peter/.vim'
-    :let target = 'sftp://peterodding.com/code/vim/profile'
-    :call Publish(sources, target, [
-        \ 'autoload/xolox/escape.vim',
-        \ 'autoload/xolox/path.vim',
-        \ 'autoload/publish.vim',
-        \ 'plugin/publish.vim',
-        \ ])
-
-Change the 'sources' and 'target' variables to reflect your situation, save
-the script as '~/publish_test.vim' and try it in Vim by executing the command
+  :set tags=~/.publish_tags
+  :let sources = '/home/peter/.vim'
+  :let target = 'sftp://peterodding.com/code/vim/profile'
+  :call Publish(sources, target, [
+      \ 'autoload/xolox/escape.vim',
+      \ 'autoload/xolox/path.vim',
+      \ 'autoload/publish.vim',
+      \ 'plugin/publish.vim',
+      \ ])
+<
+Change the 'sources' and 'target' variables to reflect your situation, save the
+script as '~/publish_test.vim' and try it in Vim by executing the command
 ':source ~/publish_test.vim'. If everything goes well Vim will be busy for a
 moment and after that you will find a bunch of syntax highlighted, interlinked
 HTML documents in the 'target' directory!

 Publishing to a remote location (website) ~
 
 As you can see from the example above it's possible to publish files directly
 to your web server using the |netrw| plug-in that's bundled with Vim, simply by
-starting the 'target' path with 'sftp://'. All you need for this to work is
-the ability to establish SCP [4] connections to your server. There are however
-two disadvantages to remote publishing over SFTP [5]:
