Prerequisites

User Kit

Prepackaged releases which install automatically and allow you to build your own operating systems with Cosmos and Visual Studio.

Dev Kit (Developer Kit)

In addition to the User Kit prerequisites, Dev Kit also needs these:

  • Visual Studio 2017 Workload: Visual Studio Extension Development
  • Inno Quick Start Pack (Free) – Install with defaults, keep Preprocessor option checked

The Dev Kit allows you to build your own operating systems, and also directly work in COSMOS source as well. Installation simply requires running a .bat file after each source sync.
