 # Warning

+This document is written **specifically for developers**: it is not intended for end users.
 
 # Assumptions
 
 - You are working on a non-critical test or development system.
-- You already have the following installed:
-  - [Docker](https://www.docker.com/).
-  - [golang](https://golang.org/dl) version 1.8.3 or newer.
-  - `make`.
-  - `gcc` (required for building the shim and runtime).
 
-- You have installed the `qemu-lite` package containing the hypervisor. This package
+# Initial setup
-  is automatically installed when you install Clear Containers, but can be
-  installed separately as well:
 
-    https://github.com/clearcontainers/runtime/wiki/Installation
+The recommended way to create a development environment is to first install the
+packaged versions of the Kata Containers components to create a working
+system:
+
+  * [Fedora\*](install/fedora-installation-guide.md)
+  * [Ubuntu\*](install/ubuntu-installation-guide.md)
+
+The installation guide instructions will install all required Kata Containers
+components, plus Docker*, the hypervisor, and the Kata Containers image and
+guest kernel.
+
+# Requirements to build individual components
+
+You need to install the following to build Kata Containers components:
+
+- [golang](https://golang.org/dl) version 1.8.3 or newer.
+
+  To view the versions of go known to work, see the `golang` entry in the
+  [versions database](https://github.com/kata-containers/runtime/blob/master/versions.yaml).
+
+- `make`.
+- `gcc` (required for building the shim and runtime).
