From 5bae00db0cbd19fc953b199978e3d45db81b40c2 Mon Sep 17 00:00:00 2001 From: Ian Wienand Date: Fri, 28 Aug 2015 11:48:58 +1000 Subject: [PATCH] Make README.rst a bit more generic I think diskimage-builder has grown somewhat since this was written, and this makes it sound like it is only useful as a TripleO component. Give a more generic overview, add a simple example to illustrate the point and generally make it clear this is a flexible solution for building disk images. Add a mention of the local documentation source.
