+Installation
+============
+
+In general, your favorite method works.  Here are some options.
+
+With pathogen.vim
+-----------------
+
+Install [pathogen.vim](https://github.com/tpope/vim-pathogen),
+then copy and paste:
+
+    git clone git://github.com/vim-ruby/vim-ruby.git ~/.vim/bundle/vim-ruby
+
+With Vundle
+-----------
+
+Install [Vundle](https://github.com/gmarik/vundle), then add the
+following to your vimrc:
+
+    Bundle 'vim-ruby/vim-ruby'
+
+With patience
+-------------
+
+Wait for an upgrade to Vim and install it.  Vim ships with the latest
+version of vim-ruby at the time of its release.  (Remember this when
+choosing another installation method.  The version you download will
+supersede the version that ships with Vim, so you will now be
+responsible for keeping it up-to-date.)
+
+If you're looking for stable releases from a particular version, you can find
+them in [github](https://github.com/vim-ruby/vim-ruby/releases).
+
+Manually
+--------
+
+[Download](https://github.com/vim-ruby/vim-ruby/archives/master) and
+extract the relevant files to `~/.vim` (or `$HOME/vimfiles` on Windows).

+
+= 2008.07.XX
+
+== Filetype Detection
+
+The IRB RC file (.irbrc) is now detected as being a Ruby file.
+
+
+= 2007.05.07
+
+== Ruby Syntax Highlighting
+
+Highlight OPTIMIZE alongside FIXME and TODO.
+
+Multiline array literals can now be folded.
+
+== Ruby Filetype Support
+
+Added mappings for [[, ]], [], ][, [m, ]m, [M, and ]M.  The first four bounce
+between class and module declarations, and the last four between method
+declarations.
+
+== eRuby Syntax Highlighting
+
+Tim Pope has taken over maintenance of the eRuby syntax file.  The subtype of
+the file is now determined dynamically from the filename, rather than being
+hardwired to HTML.  It can be overridden with b:eruby_subtype.
+
+== eRuby Filetype Support
+
+Tim Pope has taken over maintenance of the eRuby filetype plugin.  Like with
+the syntax file, the subtype is now determined dynamically.
+
+== eRuby Indenting
+
+As with the syntax file and filetype plugin, the subtype is now determined
+dynamically.
+
+== Bug Fixes
+
+Ruby syntax file
+  - when ruby_operators is set, highlight scope and range operators, and don't
+    match '>' in =>'
+  - regexp literals are highlighted after the 'else' keyword
+  - don't match [!=?] as part of a sigil prefixed symbol name
+  - allow text to appear after, and on the same line, as '=begin' in
+    rubyDocumentation regions
+  - highlight %s() ans a symbol, not a string
+  - eliminated some false positves for here docs, symbols, ASCII codes, and
+    conditionals as statement modifiers
+  - added "neus" to regexp flags
+  - Highlight punctuation variables in string interpolation, and flag invalid
+    ones as errors
+  - removed : from rubyOptionalDoLine (falsely matches on symbols)
+
+Ruby filetype plugin
+  - eliminated some false positives with the matchit patterns
+
+Ruby indent plugin
+  - ignore instance, class, and global variables named "end"
+
+
+= 2007.03.02
+
+== Omni Completion
+
+Fall back to syntax highlighting completion if Vim lacks the Ruby interface.
+
+RubyGems is now loaded by default if available.
+
+Classes are detected using ObjectSpace.  Kernel methods are included in method
+completion.
+
+Added completion in Rails views.  Rails helpers are included.  Rails migrations
+now have completion.
+
+== Ruby Syntax Highlighting
+
+Ruby code is highlighted inside interpolation regions.
+
+Symbols are now highlighted with the Constant highlight group; Constants and
+class names with the Type highlight group.
+
+Symbol names specified with a string recognise interpolation and escape
+sequences.
+
+Alias statements receive special highlighting similar to other 'definitions'.
+
+== Ruby Filetype Support
+
+Matchit support has been improved to include (), {}, and [] in the list of
+patterns so that these will be appropriately skipped when included in comments.
+
+ri has been added as the 'keywordprg' and 'balloonexpr' is set to return the
+output of ri.
+
+== eRuby Indenting
+
+Tim Pope has taken over maintenance of the eRuby indent file.  Ruby code is now
+indented appropriately.
+
+== Bug Fixes
+
+Ruby syntax file
+  - trailing whitespace is no longer included with the def, class, module
+    keywords.
+  - escaped interpolation regions should now be ignored in all cases.
+  - conditional and loop statements are now highlighted correctly in more
+    locations (where they're used as expressions).
+
+eRuby syntax file
+  - '-' trim mode block delimiters are now recognised.
+
+Omni Completion
+  - more robustness; failure to parse buffer no longer errors or prevents
+    completion.
+
+
+= 2006.07.11
+
+== Omni Completion
+
+A new omni completion function is now included which offers IntelliSense-like
+functionality. See :help ft-ruby-omni for further information.
+
+Note: This will only work with Vim 7.x, compiled with the Ruby interface
+(+ruby), and Ruby 1.8.x
+
+== Ruby Filetype Support
+
+Matchit support has been improved to include (), {}, and [] in the list of
+patterns meaning these will be appropriately skipped when included in comments.
+
+== Ruby Syntax Highlighting
+
+Operators can now be highlighted by defining the Vim global variable
+"ruby_operators".
+
+Multiline comments will now be folded. This can be disabled by defining the
+"ruby_no_comment_fold" Vim variable.
+
+== Filetype Detection
+
+RJS and RXML templates are now detected as being 'filetype=ruby'.
+
+== FAQ
+
+There is a new FAQ document included. This is a work in progress and any
+feedback would be appreciated.
+
+== Bug Fixes
+
+Ruby syntax file - if/unless modifiers after a method name ending with [?!=]
+should now be highlighted correctly.
+
+
+= 2005.10.07
+
+== Vim 6.4
+
+This release is included in Vim 6.4.
+
+== Bug Fixes
+
+Ruby filetype plugin - symbols were incorrectly being matched as match_words
+causing the matchit motion command to jump to an incorrect location in some
+circumstances.
+
+
+= 2005.10.05
+
+== Bug Fixes
+
+Ruby syntax file - allow for comments directly after module/class/def lines
+without intervening whitespace (fold markers were breaking syntax highlighting).
+
+Ruby filetype plugin - improve ordering of 'path' elements.
+
+eRuby syntax file - make use of ruby_no_expensive local to the buffer.
+
+
+= 2005.09.24
+
+== Filetype Detection
+
+The eruby filetype is now detected solely based on the file's extension. This
+was being overridden by the scripts.vim detection script.
+
+Note: Only files ending in *.rhtml are detected as filetype eruby since these
+are currently assumed to be Ruby embedded in (X)HTML only. Other filetypes
+could be supported if requested.
+
+== eRuby Indent File
+
+There is a new eRuby indent file which simply sources the HTML indent file for
+now.
+
+== eRuby Compiler Plugin 
+
+This now supports erb as the default 'makeprg'. To use eruby set the
+eruby_compiler variable to "eruby" in your .vimrc
+
+== Test::Unit Compiler Plugin
+
+This has been improved and should now display messages similar to, though more
+detailed than, the GUI test runners.
+
+== Bug Fixes
+
+A few minor bugs have been fixed in the Ruby syntax and indent files.
+
+
+= 2005.09.15
+
+== eRuby Support
+
+There are new syntax, compiler, and ftplugin files for eRuby.  This support is
+incomplete and we're keen to hear of any problems or suggestions you may have
+to improve it.
+
+== Ruby Filetype Support
+
+The Ruby filetype plugin has been improved to include as many useful settings
+as possible without intruding too much on an individual user's preferences.
+Matchit support has been improved, and the following options are now set to
+appropriate values: comments, commentstring, formatoptions, include,
+includeexpr, path, and suffixesadd
+
+== Filetype Detection
+
+The new ftdetect mechanism of Vim 6.3 is being utilized to enable filetype
+detection of eRuby files until this is officially added to the next release of
+Vim.
+
+== Installation Directories
+
+The installer script now, where possible, automatically determines both the
+user and system-wide preferences directory.
+
+== Bug Fixes
+
+A large number of bugs have been fixed in the Ruby syntax and indent files.

+## Vim-ruby
+
+This project contains Vim's runtime files for ruby support. This includes syntax
+highlighting, indentation, omnicompletion, and various useful tools and mappings.
+
+## Installation
+
+See the file [INSTALL.markdown](./INSTALL.markdown) for instructions.
+
+You might also find useful setup tips in the github wiki:
+https://github.com/vim-ruby/vim-ruby/wiki/VimRubySupport
+
+## Usage
+
+Ideally, vim-ruby should work "correctly" for you out of the box. However, ruby
+developers have varying preferences, so there are settings that control some of
+the details. You can get more information on these by using the native `:help`
+command:
+
+- [`:help vim-ruby-plugin`](./doc/ft-ruby-plugin.txt): Filetype settings and custom mappings
+- [`:help vim-ruby-indent`](./doc/ft-ruby-indent.txt): Indentation settings
+- [`:help vim-ruby-syntax`](./doc/ft-ruby-syntax.txt): Syntax-related tweaks
+- [`:help vim-ruby-omni`](./doc/ft-ruby-omni.txt): Information and settings for omni completion
+
+## Issues
+
+If you have an issue or a feature request, it's recommended to use the github
+issue tracker: https://github.com/vim-ruby/vim-ruby/issues. Try the search box
+to look for an existing issue -- it might have already been reported.
+
+If you don't have a github account or would rather contact us in a different
+way, you can find emails for individual maintainers in the
+[CONTRIBUTORS](./CONTRIBUTORS) file. They're also in the comment headers of the
+project's Vimscript files (`syntax/ruby.vim`, `indent/ruby.vim`, etc) under the
+label "Maintainer".
+
+If you're not sure who the most relevant person to contact is for your
+particular issue, you can send an email to the release coordinator, Doug Kearns
+(dougkearns at gmail.com).
+
+## Contributing
+
+Vim-ruby is a mature project, which is one way of saying it moves slowly and it
+can be a bit difficult to modify. It's far from impossible, but be warned that
+issues and PRs may take time to be handled. Partly, it's because we don't want
+to risk breaking Vim's core ruby support, partly because it takes a lot of time
+and energy to debug and fix things.
+
+Contributing a fix for an issue would be very appreciated, even if it's a
+proof-of-concept to start a conversation. Be warned that we're definitely going
+to be conservative when considering changes to vim-ruby.
+
+The code is tested using [RSpec](https://rspec.info/) and
+[Vimrunner](https://github.com/AndrewRadev/vimrunner). The tests are not
+exhaustive, but they should cover a wide variety of cases.
+
+## Project history
+
+This project began in July 2003, when the current version of Vim was 6.2. It
+was migrated from CVS in August, 2008.
+
+If you're curious about individual pre-git changes, you can read some of them
+in the (unmaintained) [NEWS](./NEWS) and/or [ChangeLog](./ChangeLog) files.

+Completion of Ruby code requires that Vim be built with |+ruby|.
+
+Ruby completion will parse your buffer on demand in order to provide a list of
+completions.  These completions will be drawn from modules loaded by "require"
+and modules defined in the current buffer.
+
+The completions provided by CTRL-X CTRL-O are sensitive to the context:
+
+          CONTEXT                          COMPLETIONS PROVIDED ~
+
+ 1. Not inside a class definition    Classes, constants and globals
+
+ 2. Inside a class definition        Methods or constants defined in the class
+
+ 3. After '.', '::' or ':'           Methods applicable to the object being
+                                       dereferenced
+
+ 4. After ':' or ':foo'              Symbol name (beginning with "foo")
+
+Notes:
+ - Vim will load/evaluate code in order to provide completions.  This may
+   cause some code execution, which may be a concern.  This is no longer
+   enabled by default, to enable this feature add >

+<   to your vimrc

+   project.  The feature is disabled by default, to enable it add >

+of the block it closes.  While useful, this feature can be expensive; if you
+experience slow redrawing (or you are on a terminal with poor color support)
+you may want to turn it off by defining the "ruby_no_expensive" variable: >
+
+	:let ruby_no_expensive = 1
+<
+In this case the same color will be used for all control keywords.
+
+						*ruby_minlines*
+
+If you do want this feature enabled, but notice highlighting errors while
+scrolling backwards, which are fixed when redrawing with CTRL-L, try setting
+the "ruby_minlines" variable to a value larger than 50: >
+
+	:let ruby_minlines = 100
+<
+Ideally, this value should be a number of lines large enough to embrace your
+largest class or module.
+
+						*ruby_spellcheck_strings*
+ Ruby: Spellchecking strings ~
+
+Ruby syntax will perform spellchecking of strings if you define
+"ruby_spellcheck_strings": >
+
+	:let ruby_spellcheck_strings = 1

+" Instructions for enabling "matchit" support:
+"
+" 1. Look for the latest "matchit" plugin at
+"
+"         http://www.vim.org/scripts/script.php?script_id=39
+"
+"    It is also packaged with Vim, in the $VIMRUNTIME/macros directory.
+"
+" 2. Copy "matchit.txt" into a "doc" directory (e.g. $HOME/.vim/doc).
+"
+" 3. Copy "matchit.vim" into a "plugin" directory (e.g. $HOME/.vim/plugin).
+"
+" 4. Ensure this file (ftplugin/ruby.vim) is installed.
+"
+" 5. Ensure you have this line in your $HOME/.vimrc:
+"         filetype plugin on
+"
+" 6. Restart Vim and create the matchit documentation:
+"
+"         :helptags ~/.vim/doc
+"
+"    Now you can do ":help matchit", and you should be able to use "%" on Ruby
+"    keywords.  Try ":echo b:match_words" to be sure.
+"
+" Thanks to Mark J. Reed for the instructions.  See ":help vimrc" for the
+" locations of plugin directories, etc., as there are several options, and it
+" differs on Windows.  Email gsinclair@soyabean.com.au if you need help.
