### Release
Provide the whole following properties in file `$rootDir/local.properties`:

``` ini
storeFile=<Yours>
storePassword=<Yours>
keyAlias=<Yours>
keyPassword=<Yours>
```

The location of `storeFile` can be `../keys/release.jks`.  
It has been already ignored in file `$rootDir/.gitingore` by default.  
So you can put your own private certificate or signing key there safely.
