## Installation

First install the gems.
#### Pre-Commit Checkstyle

#### Java Checkstyle Plugin

    gem install java-checkstyle

##### (optional) If you use RVM
Take a look here [Install with RVM](https://github.com/jish/pre-commit#rvm)

### Configuring
Use the pre-commit command to generate a stub pre-commit hook.
Inside folder of your git repo:

```bash
pre-commit install
```

It will create a .git/hooks/pre-commit script which will check your git config and run checks that are enabled.

#### Enabling checks

``` bash
pre-commit enable git checks checkstyle
```

### Result
Every time you try to commit some java code with style errors it will validate
for you ensuring that your code will be always awesome.
