+1. Overview ~
+
+    The Haskell mode plugins provide advanced support for Haskell development
+    using GHC/GHCi on Windows and Unix-like systems. The functionality is
+    based on Haddock-generated library indices, on GHCi's interactive
+    commands, or on simply activating (some of) Vim's built-in program editing
+    support in Haskell-relevant fashion. These plugins live side-by-side with
+    the pre-defined |syntax-highlighting| support for |haskell| sources, and
+    any other Haskell-related plugins you might want to install (see
+    |haskellmode-resources|).
+
+    The Haskell mode plugins consist of three filetype plugins (haskell.vim,
+    haskell_doc.vim, haskell_hpaste.vim), which by Vim's |filetype| detection
+    mechanism will be auto-loaded whenever files with the extension '.hs' are
+    opened, and one compiler plugin (ghc.vim) which you will need to load from
+    your vimrc file (see |haskellmode-settings|).
+
+
+                                                    *haskellmode-requirements*
+1.1 Runtime Requirements ~
+
+    The plugins require a recent installation of GHC/GHCi. The functionality
+    derived from Haddock-generated library indices also requires a local
+    installation of the Haddock documentation for GHC's libraries (if there is
+    no documentation package for your system, you can download a tar-ball from
+    haskell.org), as well as an HTML browser (see |haddock_browser|). If you 
+    want to use the experimental hpaste interface, you will also need Wget.
+
+    * GHC/GHCi ~
+      Provides core functionality. http://www.haskell.org/ghc
+
+    * HTML library documentation files and indices generated by Haddock ~
+      These usually come with your GHC installation, possibly as a separate
+      package. If you cannot get them this way, you can download a tar-ball
+      matching your GHC version from  http://www.haskell.org/ghc/docs/
+
+    * HTML browser with basic CSS support ~
+      For browsing Haddock docs.
+
+    * Wget ~
+      For interfacing with http://hpaste.org.
+
+      Wget is widely available for modern Unix-like operating systems. Several
+      ports also exist for Windows, including:
+
+      - Official GNU Wget (natively compiled for Win32)
+        http://www.gnu.org/software/wget/#downloading
+
+      - UnxUtils Wget (natively compiled for Win32, bundled with other ported
+        Unix utilities)
+        http://sourceforge.net/projects/unxutils/
+
+      - Cygwin Wget (emulated POSIX in Win32, must be run under Cygwin)
+        http://cygwin.com/packages/wget/
+
+                                                    *haskellmode-quickref*

+2. Settings ~
+
+    The plugins try to find their dependencies in standard locations, so if
+    you're lucky, you will only need to set |compiler| to ghc, and configure
+    the location of your favourite web browser. You will also want to make
+    sure that |filetype| detection and |syntax| highlighting are on. Given the
+    variety of things to guess, however, some dependencies might not be found
+    correctly, or the defaults might not be to your liking, in which case you
+    can do some more fine tuning. All of this configuration should happen in
+    your |vimrc|.

+                                                 *compiler-ghc* *ghc-compiler*
+    To use the features provided by the GHC |compiler| plugin, use the
+    following |autocommand| in your vimrc:
+>
+        au BufEnter *.hs compiler ghc
+<
+                                                                       *g:ghc*
+    If the compiler plugin can't locate your GHC binary, or if you have
+    several versions of GHC installed and have a preference as to which binary
+    is used, set |g:ghc|:
+>
+        :let g:ghc="/usr/bin/ghc-6.6.1"
+<
+                                                           *g:haddock_browser*
+    The preferred HTML browser for viewing Haddock documentation can be set as
+    follows:
+>
+        :let g:haddock_browser="/usr/bin/firefox"
+<
+
+                                                   *haskellmode-settings-fine*
+2.2 Fine tuning - more configuration options ~
+
+    Most of the fine tuning is likely to happen for the haskellmode_doc.vim
+    plugin, so you can check the current settings for this plugin via the
+    command |:DocSettings|. If all the settings reported there are to your
+    liking, you probably won't need to do any fine tuning.
+
+                                                *g:haddock_browser_callformat*
+    By default, the web browser|g:haddock_browser| will be started
+    asynchronously (in the background) on Windows or when vim is running in a
+    GUI, and synchronously (in the foreground) otherwise. These settings seem
+    to work fine if you are using a console mode browser (eg, when editing in
+    a remote session), or if you are starting a GUI browser that will launch
+    itself in the background. But if these settings do not work for you, you
+    can change the default browser launching behavior.
+
+    This is controlled by |g:haddock_browser_callformat|. It specifies a
+    format string which uses two '%s' parameters, the first representing the
+    path of the browser to launch, and the second is the documentation URL
+    (minus the protocol specifier, i.e. file://) passed to it by the Haddock
+    plugin.  For instance, to launch a GUI browser on Unix-like systems and
+    force it to the background (see also |shellredir|):
+>
+        :let g:haddock_browser_callformat = '%s file://%s '.printf(&shellredir,'/dev/null').' &'
+<
+                                                            *g:haddock_docdir*
+    Your system's installed Haddock documentation for GHC and its libraries
+    should be automatically detected. If the plugin can't locate them, you
+    must point |g:haddock_docdir| to the path containing the master index.html
+    file for the subdirectories 'libraries', 'Cabal', 'users_guide', etc.:
+>
+        :let g:haddock_docdir="/usr/local/share/doc/ghc/html/"
+<
+                                                      *g:haddock_indexfiledir*
+    The information gathered from Haddock's index files will be stored in a
+    file called 'haddock_index.vim' in a directory derived from the Haddock
+    location, or in $HOME. To configure another directory for the index file,
+    use: 
+>
+        :let g:haddock_indexfiledir="~/.vim/"
+<
+                                                                      *g:wget*
+    If you also want to try the experimental hpaste functionality, you might
+    you need to set |g:wget| before the |hpaste| plugin is loaded (unless wget
+    is in your PATH):
+>
+        :let g:wget="C:\Program Files\wget\wget.exe"
+<
+
+    Finally, the mappings actually use|<LocalLeader>|behind the scenes, so if
+    you have to, you can redefine|maplocalleader|to something other than '_'.
+    Just remember that the docs still refer to mappings starting with '_', to
+    avoid confusing the majority of users!-)

+3. GHC Compiler Integration ~
+
+    The GHC |compiler| plugin sets the basic |errorformat| and |makeprg| to
+    enable |quickfix| mode using GHCi, and provides functionality for show
+    info (|_si|), show type (|_t| or mouse |balloon|), add type declaration
+    (|_T|), create tag file (|_ct|), and insert-mode completion
+    (|i_CTRL-X_CTRL-O|) based on GHCi browsing of the current and imported
+    modules. 
+
+    To avoid frequent calls to GHCi, type information is cached in Vim. The
+    cache will be populated the first time a command depends on it, and will
+    be refreshed every time a |:make| goes through without generating errors
+    (if the |:make| does not succeed, the old types will remain available in
+    Vim).  You can also unconditionally force reloading of type info using
+    |:GHCReload| (if GHCi cannot load your file, the type info will be empty).
+
+
+    In addition to the standard|quickfix| commands, the GHC compiler plugin
+    provides:
+
+                                                                  *:GHCReload*
+:GHCReload              Reload modules and unconditionally refresh cache of
+                        type info. Usually, |:make| is prefered, as that will
+                        refresh the cache only if GHCi reports no errors, and
+                        show the errors otherwise.
+
+                                                           *:GHCStaticOptions*
+:GHCStaticOptions       Edit the static GHC options (more generally, options
+                        that cannot be set by in-file OPTIONS_GHC pragmas)
+                        for the current buffer. Useful for adding hidden 
+                        packages (-package ghc), or additional import paths
+                        (-isrc; you will then also want to augment |path|).
+                        If you have static options you want to set as
+                        defaults, you could use b:ghc_staticoptions, eg:
+>
+                        au FileType haskell let b:ghc_staticoptions = '-isrc'
+                        au FileType haskell setlocal path += src
+<
+
+                                                                       *:GHCi*
+:GHCi {command/expr}    Run GHCi commands/expressions in the current module.                  
+
+                                                                         *_ct*
+_ct                     Create |tags| file for the current Haskell source
+                        file. This uses GHCi's :ctags command, so it will work
+                        recursively, but will only list tags for exported
+                        entities.
+
+                                                                        *_opt*
+_opt                    Shows a menu of frequently used GHC compiler options 
+                        (selecting an entry adds the option as a pragma to the
+                        start of the file). Uses popup menu (GUI) or :emenu
+                        and command-line completion (CLI).
+
+                                                                       *_lang*
+_lang                   Shows a menu of the LANGUAGE options supported by GHC
+                        (selecting an entry adds the language as a pragma to 
+                        the start of the file). Uses popup menu (GUI) or
+                        :emenu and command-line completion (CLI).
+
+                                                                         *_si*
+_si                     Show extended information for the name under the
+                        cursor. Uses GHCi's :info command. Output appears in
+                        |preview-window| (when done, close with |:pclose|).
+
+                                                                          *_t*
+_t                      Show type for the name under the cursor. Uses cached
+                        info from GHCi's :browse command.
+
+                                                                          *_T*
+_T                      Insert type declaration for the name under the cursor.

+CTRL-X CTRL-O           Standard insert-mode omni-completion based on the
+                        cached type info from GHCi browsing current and
+                        imported modules. Only names from the current and from
+                        imported modules are included (the completion menu
+                        also show the type of each identifier).

+4. Haddock Integration ~
+
+    Haskell mode integrates with Haddock-generated HTML documentation,
+    providing features such as navigating to the Haddock entry for the
+    identifier under the cursor (|_?|), completion for the identifier under
+    the cursor (|i_CTRL-X_CTRL-U|), and adding import statements (|_i| |_im|
+    |_iq| |_iqm|) or module qualifier (|_.|) for the identifier under the
+    cursor.
+
+    These commands operate on an internal Haddock index built from the
+    platform's installed Haddock documentation for GHC's libraries. Since
+    populating this index takes several seconds, it should be stored as a 
+    file called 'haddock_index.vim' in the directory specified by
+    |g:haddock_indexfiledir|.
+
+    Some commands present a different interface (popup menu or command-line
+    completion) according to whether the current Vim instance is graphical or
+    console-based (actually: whether or not the GUI is running). Such
+    differences are marked below with the annotations (GUI) and (CLI),
+    respectively.
+
+    |:DocSettings| shows the settings for this plugin. If you are happy with
+    them, you can call |:ExportDocIndex| to populate and write out the
+    documentation index (should be called once for every new version of GHC).
+
+                                                                *:DocSettings*

+5. Hpaste Integration ~
+
+    This experimental feature allows browsing and posting to
+    http://hpaste.org, a Web-based pastebin tailored for Haskell code.
+
+
+                                                                *:HpasteIndex*
+:HpasteIndex            Read the most recent entries from hpaste.org. Show an
+                        index of the entries in a new buffer, where ',r' will
+                        open the current highlighted entry [and ',p' will
+                        annotate it with the current buffer].
+
+                                                              *:HpastePostNew*
+:HpastePostNew          Submit current buffer as a new hpaste entry.
+                        [This, and ',p' above, are temporarily disabled, 
+                         needs update to new hpaste.org layout]

+6. Additional Resources ~
+
+    An quick screencast tour through of these plugins is available at:
+
+    http://projects.haskell.org/haskellmode-vim/screencasts.html
+
+    Other Haskell-related Vim plugins can be found here:
+
+    http://www.haskell.org/haskellwiki/Libraries_and_tools/Program_development#Vim
+
+    Make sure to read about Vim's other program-editing features in its online
+    |user-manual|. Also have a look at Vim tips and plugins at www.vim.org -
+    two other plugins I tend to use when editing Haskell are AlignPlugin.vim
+    (to line up regexps for definitions, keywords, comments, etc. in
+    consecutive lines) and surround.vim (to surround text with quotes,
+    brackets, parentheses, comments, etc.).
