## Buildflags
### Logging
Building via `make` only logs errors (via OSReport). To enable logging via the [LoggingModule](https://github.com/wiiu-env/LoggingModule) set `DEBUG` to `1` or `VERBOSE`.
`make` Logs errors only (via OSReport).
`make DEBUG=1` Enables information and error logging via [LoggingModule](https://github.com/wiiu-env/LoggingModule).
`make DEBUG=VERBOSE` Enables verbose information and error logging via [LoggingModule](https://github.com/wiiu-env/LoggingModule).
## Building
Make you to have [wut](https://github.com/devkitPro/wut/) installed and use the following command for build:
