+This directory contains scripts/files to bootstrap a `etcd` cluster.
+
+In the local, hyperkit based, setup, we use a `etcd` running in a
+Docker for Mac container to bootstrap the cluster. For a cloud based demo, we'd use `https://discovery.etcd.io`. The host/DfM side is setup with [dfm-setup.sh](./dfm-setup.sh).
+
+The moby `etcd` package is build with [build-pkg.sh](./build-pkg.sh). It take the official `etcd` container and adds a [script](./etcd.sh) to start `etcd`.
+
+To run (for now):
+
+- Start the etcd bootstrap container in on window:
+```
+./dfm-setup.sh
+```
+
+- In another window build/run the moby image:
+```
+./build-pkg.sh
+moby build etcd
+moby run etcd
+```
