+vim-flake8 ![Project status](http://stillmaintained.com/nvie/vim-flake8.png)
+==========
+
+Installation
+------------
+Use [vim-pathogen](https://github.com/tpope/vim-pathogen) if you're not using
+it already.  Then, simply put the contents of this repository in your
+`~/.vim/bundle` directory.
+
+Usage
+-----
+1. Open a Python file
+2. Press `<F7>` to run `flake8` on it
+
+It shows the errors inside a quickfix window, which will allow your to quickly
+jump to the error locations by simply pressing [Enter].
+
+
+Customization
+-------------
+If you don't want to use the `<F7>` key for flake8-checking, simply remap it to
+another key.  It autodetects whether it has been remapped and won't register
+the `<F7>` key if so.  For example, to remap it to `<F3>` instead, use:
+
+    autocmd FileType python map <buffer> <F3> :call Flake8()<CR>
+
+
+Tips
+----
+A tip might be to run the Flake8 check every time you write a Python file, to
+enable this, add the following line to your `.vimrc` file (thanks
+[Godefroid](http://github.com/gotcha)!):
+
+    autocmd BufWritePost *.py call Flake8()
+
+
+This plugin goes well together with the following plugin:
+
+- [PyUnit](http://github.com/nvie/vim-pyunit) (unit test helper under `<F8>`
+  and `<F9>`)
