+## Download the full CORD source tree and optionally apply Gerrit patchsets
+
+The `bootstrap-repo.sh` script installs the `repo` tool, uses it to
+download the CORD source tree, and optionally applies one or more
+patchsets from Gerrit to the tree. It may be useful when
+bootstrapping a new environment for development or testing.
+
+Usage:
+```
+bootstrap-repo.sh [-p <project:change/revision>]
+```
