+## jscs.vim
+
+A vim plugin that wraps `jscs -x` into a `:Format` command, for use within Vim.
+Can accept range or operate on the whole file.
+
+### Installation
+
+- First, you need jscs installed globally: npm install jscs -g
+- Extract the files and put them in your VIM directory (usually `~/.vim/`)
+
+If you don't have a preferred installation method, I recommend installing
+[vim-plug](https://github.com/junegunn/vim-plug) and using the following configuration:
+
+    Plug 'mklabs/jscs.vim', { 'do': 'npm i jscs -g' }
+
+so that vim-plug takes care of installing jscs for you.
+
+### :Format
+
+The single command exposed by this plugin.
+
+Accepts a range and is usable in Visual mode.
+
+Ex.
+
+    plugin.commandSync('Cmd', {
+        range: '',
+        nargs: '*',
+    }, function( nvim, args, range, cb ) {
+        try {
+            incrementCalls()
+            nvim.setCurrentLine(
+                fmt('Command: Called', numCalls, 'times, args:', args, 'range:', range),
+                cb )
+        } catch ( err ) {
+            cb( err )
+        }
+    })
+
+Running `:Format` while run jscs in fix mode on the whole file and replace the current buffer with the result.
+
+### Configuration
+
+The default configuration uses airbnb styleguide, you can change the configuration used by jscs with:
+
+    let g:jscs_config = "/path/to/.jscsrc"
