# Configure BladeRunner

This page describes some of the areas that you can configure within BladeRunner.

## Logging

When you start BladeRunner, you can set a logging level to control. By default, BladeRunner writes basic informational messages to standard output. You can have more detailed messages written by adding the `--verbose` or `--debug` (most detailed) flags as shown below:

* `bladerunner start --verbose`
* `bladerunner start --debug`

```

```

## Ports

Within the BladeRunner installation directory, navigate to the `conf` directory. Within this directory, open the file `bladerunner.conf` in a text editor.

Locate the property `jettyPort`, and edit the port number as required.

## Input encoding

Within the BladeRunner installation directory, navigate to the `conf` directory. Within this directory, open the file `bladerunner.conf` in a text editor.

Locate the property `defaultInputEncoding`, and edit the default encoding as required.

## Compression levels

Within the BladeRunner installation directory, navigate to the `conf` directory. Within this directory, open the file `bladerunner.conf` in a text editor.

```
bladerunner war -m closure-simple
```
