 -*- llvm/utils/vim/README -*-
 
-These are syntax highlighting files for the VIM editor. Included are:
+This directory contains settings for the vim editor to work on llvm *.ll and
+tablegen *.td files. It comes with filetype detection rules in the (ftdetect),
+syntax highlighting (syntax), some minimal sensible default settings (ftplugin)
+and indentation plugins (indent).
 
-* llvm.vim
-
-  Syntax highlighting mode for LLVM assembly files. To use, copy `llvm.vim' to
-  ~/.vim/syntax and add this code to your ~/.vimrc :
-
-  augroup filetype
-    au! BufRead,BufNewFile *.ll     set filetype=llvm
-  augroup END
-
-* tablegen.vim
-
-  Syntax highlighting mode for TableGen description files. To use, copy
-  `tablegen.vim' to ~/.vim/syntax and add this code to your ~/.vimrc :
-
-  augroup filetype
-    au! BufRead,BufNewFile *.td     set filetype=tablegen
-  augroup END
-
-
-If you prefer, instead of making copies you can make symlinks from
-~/.vim/syntax/... to the syntax files in your LLVM source tree. Apparently
-this did not work with older versions of vim however, so if this doesn't
-work you may need to make actual copies of the files.
-
-Another option, if you do not already have a ~/.vim/syntax directory, is
-to symlink ~/.vim/syntax itself to llvm/utils/vim .
+To install copy all subdirectories to your $HOME/.vim or if you prefer create
+symlinks to the files here. Do not copy the vimrc file here it is only meant as an inspiration and starting point for those working on llvm c++ code.
 
 Note: If you notice missing or incorrect syntax highlighting, please contact
 <llvmbugs [at] cs.uiuc.edu>; if you wish to provide a patch to improve the
