+# CORD Guide
+
+This is a curated set of guides that describe how to install, operate, test,
+and develop [CORD](https://opencord.org).
+
+CORD is a community-based open source project. In addition to this guide, you
+can find information about this community, its projects, and its governance on
+the [CORD wiki](https://wiki.opencord.org). This includes early white papers
+and design notes that have shaped [CORD's
+architecture](https://wiki.opencord.org/display/CORD/Documentation).
+
+## Making Changes to Documentation
+
+The [http://guide.opencord.org](http://guide.opencord.org) website is built
+using the [GitBook Toolchain](https://toolchain.gitbook.com/), with the
+documentation root in
+[build/docs](https://github.com/opencord/cord/blob/{{ book.branch }}/docs) in a
+checked out source tree.  It is build with `make`, and requires that gitbook,
+python, and a few other tools are installed.
+
+Source for individual guides is available in the [CORD code
+repository](https://gerrit.opencord.org); look in the `docs` directory of each
+project, with the documentation rooted in `build/docs`. Updates and
+improvements to this documentation can be submitted through Gerrit.
