unite-outline is a unite.vim's source which provides your Vim's buffer with the outline view. It parses the current buffer's content and extracts headings from the buffer. And then it shows the list of the headings using unite.vim's interface. When you select a heading from the list, you can jump to the corresponding location in the buffer.

The methods for extracting headings can be implemented for each individual filetypes. You can customize them as you like with Vim script and can also create new ones for unsupported filetypes.

Install the distributed files into your Vim script directory which is usually $HOME/.vim, or $HOME/vimfiles on Windows.

You can show the heading list of the current buffer with ":Unite outline" command if you succeeded the installation (and unite-outline supports the filetype of the buffer).

To show the heading list of the current buffer, execute |:Unite| command with "outline" as a source parameter.
