+Minimal clang-rename integration with Vim.
+
+Before installing make sure one of the following is satisfied:
+
+* clang-rename is in your PATH
+* `g:clang_rename_path` in ~/.vimrc points to valid clang-rename executable
+* `binary` in clang-rename.py points to valid to clang-rename executable
+
+To install, simply put this into your ~/.vimrc
+
+    map ,cf :pyf <path-to>/clang-include-fixer.py<cr>
+
+All you have to do now is to place a cursor on a variable/function/class which
+you would like to rename and press ',cf'. You will be promted a new name if the
+cursor points to a valid symbol.
