# Quick Start

{% hint style="info" %}
**Start by following the install** [**instructions**](/installing.md)**.**
{% endhint %}

## Discover your hardware

```dart
import 'package:system_info2/system_info2.dart';

if (SysInfo.operatingSystemName == "Ubuntu") {
  log.info("We love Ubuntu users");
}

if (SysInfo.userSpaceBitness == 32) {
  log.info("Dart VM runs as a 32-bit process");
}
```

The system\_info2 package provides a variety of details:

```dart
import 'package:system_info2/system_info2.dart';

void main() {
  print('Kernel architecture     : ${SysInfo.kernelArchitecture}');
  print('Kernel bitness          : ${SysInfo.kernelBitness}');
  print('Kernel name             : ${SysInfo.kernelName}');
  print('Kernel version          : ${SysInfo.kernelVersion}');
  print('Operating system name   : ${SysInfo.operatingSystemName}');
  print('Operating system version: ${SysInfo.operatingSystemVersion}');
  print('User directory          : ${SysInfo.userDirectory}');
  print('User id                 : ${SysInfo.userId}');
  print('User name               : ${SysInfo.userName}');
  print('User space bitness      : ${SysInfo.userSpaceBitness}');
  final processors = SysInfo.processors;
  print('Number of processors    : ${processors.length}');
  for (var processor in processors) {
    print('  Architecture          : ${processor.architecture}');
    print('  Name                  : ${processor.name}');
    print('  Socket                : ${processor.socket}');
    print('  Vendor                : ${processor.vendor}');
  }
  print(
      'Total physical memory   : ${SysInfo.getTotalPhysicalMemory() ~/ MEGABYTE} MB');
  print(
      'Free physical memory    : ${SysInfo.getFreePhysicalMemory() ~/ MEGABYTE} MB');
  print(
      'Total virtual memory    : ${SysInfo.getTotalVirtualMemory() ~/ MEGABYTE} MB');
  print(
      'Free virtual memory     : ${SysInfo.getFreeVirtualMemory() ~/ MEGABYTE} MB');
  print(
      'Virtual memory size     : ${SysInfo.getVirtualMemorySize() ~/ MEGABYTE} MB');
}

const int MEGABYTE = 1024 * 1024;

```
