This support based on latest working draft, not dev edition. The dev
edition has removed `instant` value, but it is not a big problem.

This resolves #33.

-TITLE

-
 vim-css3-syntax
+===============
 
-
-DESCRIPTION
-===========
-
-Add CSS3 syntax support to vim's built-in `syntax/css.vim`.
+Add CSS3 syntax support to [Vim][1]'s built-in `syntax/css.vim`.
 
 
 INSTALLATION
-============
+------------
 
-Extract vim-css3-syntax.tar.gz and copy contents to `~/.vim` directory.
+I **strongly** recommend to install this plugin on *Vim 7.4 or higher with
+default runtime files*.
 
 
-Git and pathogen
-================
+### Manual Installation
+
+Download from GitHub, extract `vim-css3-syntax.tar.gz`, and copy the contents to
+your `~/.vim` directory.
+
+
+### Installing with Git and pathogen
 
     $ cd ~/.vim/bundle
-    $ git clone https://hail2u@github.com/hail2u/vim-css3-syntax.git
+    $ git clone https://github.com/hail2u/vim-css3-syntax.git
 
 
-HISTORY
-=======
+NOTES
+-----
 
-v0.1
-----
-  * Initial release
+### Highlighting problems on: `vertical-align`, `box-shadow`, and others
+
+Some properties do not highlight correctly by default. This is a limitation of
+Vim's highlight priority mechanism. To fix this problems, put following lines in
+your `~/.vim/after/css.vim`:
+
+    setlocal iskeyword+=-
+
+Or in your `~/.vimrc`:
+
+    augroup VimCSS3Syntax
+      autocmd!
+
+      autocmd FileType css setlocal iskeyword+=-
+    augroup END
+
+This setting have side effects. So, use it at your own risk.
+
+
+### Vendor Prefixes
+
+I do not plan to support CSS3 properties (or functions) with vendor prefixes,
+such as `-webkit-` or `-moz-`, etc. These are hard to maintain because they are:
+
+  * Added frequently
+  * Changed unexpectedly
+  * Removed silently
+
+These must be supported by separate syntax plugins (Vim 7.4's default CSS syntax
+file supports this). If you want to highlight prefixed properties or functions
+manually, `:highlight` and `:match` would help:
+
+    :highlight VendorPrefix guifg=#00ffff gui=bold
+    :match VendorPrefix /-\(moz\|webkit\|o\|ms\)-[a-zA-Z-]\+/
+
+These commands highlight vendor prefixed properties and functions instantly with
+cyan and bold (on gVim).
+
+
+### CSS Preprocessors: [Sass][2], [LESS][3], and [Stylus][4]
+
+`vim-css3-syntax` supports Sass's SCSS syntax only. If you want to use this
+plugin with LESS, install [VIM-LESS][5]. Sass's indent syntax and Stylus are not
+supported.
+
+
+### Media Queries
+
+I drop Media Queries Level 3 support in v0.12.0. There is no easy way to support
+Media Queries properly with `after` syntax plugin like this one, sorry. If you
+want to highlight Media Queries correctly, you must update Vim to 7.4+ or
+install [JulesWang/css.vim][6].
