-# rpm-ostree
-A system to compose RPMs on a server side into an
-[OSTree](https://wiki.gnome.org/Projects/OSTree)
-repository, and a client side tool to perform updates.
+# rpm-ostree Overview
+
+New! See the docs online at [Read The Docs (rpm-ostree)](https://rpm-ostree.readthedocs.org/en/latest/ )
+
+-----
+
+rpm-ostree is a hybrid image/package system.  It uses
+[OSTree](https://wiki.gnome.org/Projects/OSTree) as an image format,
+and uses RPM as a component model.
 
 The project aims to bring together a hybrid of image-like upgrade
 features (reliable replication, atomicity), with package-like
-flexibility (seeing package sets inside trees, layering, partial live
-updates).
+flexibility (introspecting trees to find package sets, package
+layering, partial live updates).
 
-## rpm-ostree is in beta!
-While many of the underlying technologies here are stable,
-if you are considering using this in your organization, you
-should perform a careful evaluation of the whole stack.  Software
-updates are obviously critical, and touch on many areas of concern.
+**Features:**
+
+ - Atomic upgrades and rollback for host system updates
+ - A server side tool to consume RPMs and commit them to an OSTree repository
+ - A system daemon to consume ostree commits as updates
+
+Projects using rpm-ostree
+-------------------------
+
+[Project Atomic](http://www.projectatomic.io/) uses rpm-ostree to
+provide a minimal host for Docker formatted Linux containers.
+Replicating a base immutable OS, then using Docker for applications.
+
+Building
+--------
+
+Releases are available as GPG signed git tags, and most recent
+versions support extended validation using
+[git-evtag](https://github.com/cgwalters/git-evtag).
+
+However, in order to build from a git clone, you must update the
+submodules.  If you're packaging and want a tarball, I recommend using
+a "recursive git archive" script.  There are several available online;
+[this code](https://git.gnome.org/browse/ostree/tree/packaging/Makefile.dist-packaging#n11)
+in OSTree is an example.
+
+Once you have a git clone or recursive archive, building is the
+same as almost every autotools project:
+
+```
+env NOCONFIGURE=1 ./autogen.sh
+./configure --prefix=...
+make
+make install DESTDIR=/path/to/dest
+```

 Treefile
 --------
 
+A "treefile" is a made up term for a JSON-formatted specification used
+as input to `rpm-ostree compose tree` to bind "set of RPMs with
+configuration" to "OSTree commit".
+
+It's recommended to keep them in git, and set up a CI system like
+Jenkins to operate on them as it changes.
+
+It supports the following parameters:
+
  * `ref`: string, mandatory: Holds a string which will be the name of
    the branch for the content.
