-NOTHING TO SEE HERE
+cloud-agent for OpenBSD
-===================
+=======================
 
-*...yet*
+**This is just experimental.  Be warned.**
+
+This is a simple OpenBSD-specific agent that aims to handle
+provisioning and cloud initialization on public clouds such as
+Microsoft Azure and Amazon AWS.  For OpenBSD on Azure, it is a minimal
+alternative to the [WALinuxAgent](https://github.com/Azure/WALinuxAgent/).
+
+Prerequisites
+-------------
+
+* OpenBSD 6.1 or higher, nothing else.
+
+Files
+-----
+
+* `/usr/local/libexec/cloud-agent`
+* `/usr/local/bin/cms`
+
+The CMS binary is a port of OpenSSL's CMS tool to LibreSSL.  LibreSSL
+has removed CMS which is required by Azure.
+
+Usage
+-----
+
+Installation is easy, `cloud-agent` detects the cloud type automatically.
+
+* On Microsoft Azure, create a file `/etc/hostname.hvn0`
+
+* On Amazon AWS, create a file `/etc/hostname.xnf0`
+
+* On OpenBSD VMM (with meta-data), create a file `/etc/hostname.vio0`
+
+* The content of the fill is identical for all of them:
+
+		dhcp
+		!/usr/local/libexec/cloud-agent "\$if"
