+For Vim users there are two main approaches, one that leans on [sbdchd](https://github.com/sbdchd)/[neoformat](https://github.com/sbdchd/neoformat), which has the advantage of leaving the cursor in the same position despite changes, or a vanilla approach which can only approximate the cursor location, but might be good enough for your needs.
+
+#### Vanilla approach
 
 Vim users can add the following to their `.vimrc`:
 
-```
+```vim
 autocmd FileType javascript set formatprg=prettier\ --stdin
 ```

 (although it's not guaranteed that it will be restored to the same
 place in the code since it may have moved):
 
-```
+```vim
 autocmd BufWritePre *.js exe "normal! gggqG\<C-o>\<C-o>"
 ```
 
+#### Neoformat approach
+
+Add [sbdchd](https://github.com/sbdchd)/[neoformat](https://github.com/sbdchd/neoformat) to your list based on the tool you use:
+
+```vim
+Plug 'sbdchd/neoformat'
+```
+
+Then make Neoformat run on save:
+
+```vim
+autocmd BufWritePre *.js Neoformat
+```
+
+#### Customizing prettier in Vim
+
+If your project requires settings other than the default prettier settings you can pass arguments to do so in your `.vimrc` or [vim project](http://vim.wikia.com/wiki/Project_specific_settings), you can do so:
+
+```vim
+autocmd FileType javascript set formatprg=prettier\ --stdin\ --parser\ flow\ --single-quote\ --trailing-comma\ es5
+```
+
+Each command needs to be escaped with `\`. If you are using Neoformat and you want it to recognize your formatprg settings you can also do that by adding the following to your `.vimrc`:
+
+```vim
+" Use formatprg when available
+let g:neoformat_try_formatprg = 1
+```
