+## vim-prettier
+
+A vim plugin wrapper for prettier, pre-configured with custom default prettier settings.
+
+### INSTALL 
+
+Install with [vim-plug](https://github.com/junegunn/vim-plug), assumes node and yarn|npm installed globally.
+
+```
+" yarn install | npm install
+Plug 'mitermayer/vim-prettier', { 'do': 'yarn install', 'for': 'javascript' } 
+```
+
+If using other vim plugin managers or doing manual setup make sure to have `prettier` installed globally or go to your vim-prettier directory and either do `npm install` or `yarn install`
+
+## Prettier Executable resolution
+
+When installed via vim-plug, a default prettier executable is installed inside vim-prettier.
+
+vim-prettier executable resolution:
+
+1. Tranverse parents and search for Prettier installation inside `node_modules`
+2. Look for a global prettier installation
+3. Use locally installed vim-prettier prettier executable
+
+## USAGE
+
+Formats the entire buffer
+
+```
+:Prettier
+```
+
+Disable auto formatting of javascript files that have "@format" tag 
+
+```
+let g:prettier#autoformat = 0
+```
+
+Enable vim-prettier to run in javascript files without the "@format" doc tag 
+
+```
+autocmd BufWritePre *.js call prettier#Prettier()
+```
+
+Overwrite default configuration
+
+```
+" max line lengh that prettier will wrap on
+g:prettier#config#print_width = 80
+
+" number of spaces per indentation level
+g:prettier#config#tab_width = 2
+
+" use tabs over spaces
+g:prettier#config#use_tabs = 0
+
+" print semicolons
+g:prettier#config#semi = 1
+
+" single quotes over double quotes
+g:prettier#config#single_quote = 1
+
+" print spaces between brackets
+g:prettier#config#bracket_spacing = 0
+
+" put > on the last line instead of new line
+g:prettier#config#jsx_bracket_same_line = 1
+
+" none|es5|all
+g:prettier#config#trailing_comma = 'all'
+
+" flow|babylon
+g:prettier#config#parser = 'flow'
+
+```
+### REQUIREMENT(S) 
+
+If prettier installation can't be found no code formatting will happen
