+# vim-phpstan
+
+A Vim plugin for [PHPStan](https://github.com/phpstan/phpstan). It calls `phpstan` to do static analysis of your PHP code and displays the errors in Vim's quickfix list.
+
+See `:help quickfix` for more on how to use the quickfix.
+
+# Usage
+
+Call the `PHPStanAnalyse` command and pass the directories you want analysed as arguments:
+
+``` vim
+:PHPStanAnalyse src test
+```
+
+And the quickfix list will be populated with something like this:
+
+![vim phpstan quickfix screenshot](https://github.com/robertbasic/vim-phpstan/blob/master/vim-phpstan-qf.png)
+
+# Installation
+
+Using [vim-plug](https://github.com/junegunn/vim-plug):
+
+`Plug 'robertbasic/vim-phpstan'`
+
+# Configuration
+
+You can configure the level PHPStan uses. By default the level is 2.
+
+`let g:phpstan_analyse_level = 4` in your `.vimrc` file to change the level to fit your needs.
