+	//    `CreateVolume` calls for the same name do not result in more

+	//    error recovery logic could result in multiple (unused) volumes
+	//    being provisioned.
+	//    In the case of error, the CO MUST handle the gRPC error codes
+	//    per the recovery behavior defined in the "CreateVolume Errors"
+	//    section below.
+	//    The CO is responsible for cleaning up volumes it provisioned
+	//    that it no longer needs. If the CO is uncertain whether a volume
+	//    was provisioned or not when a `CreateVolume` call fails, the CO
+	//    MAY call `CreateVolume` again, with the same name, to ensure the
+	//    volume exists and to retrieve the volume's `volume_id` (unless
+	//    otherwise prohibited by "CreateVolume Errors").
+	// 2) Suggested name - Some storage systems allow callers to specify
+	//    an identifier by which to refer to the newly provisioned
+	//    storage. If a storage system supports this, it can optionally
+	//    use this name as the identifier for the new volume.

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+# [csi-release-tools](https://github.com/kubernetes-csi/csi-release-tools)
+
+These build and test rules can be shared between different Go projects
+without modifications. Customization for the different projects happen
+in the top-level Makefile.
+
+The rules include support for building and pushing Docker images, with
+the following features:
+ - one or more command and image per project
+ - push canary and/or tagged release images
+ - automatically derive the image tag(s) from repo tags
+ - the source code revision is stored in a "revision" image label
+ - never overwrites an existing release image
+
+Usage
+-----
+
+The expected repository layout is:
+ - `cmd/*/*.go` - source code for each command
+ - `cmd/*/Dockerfile` - docker file for each command or
+   Dockerfile in the root when only building a single command
+ - `Makefile` - includes `release-tools/build.make` and sets
+   configuration variables
+ - `.travis.yml` - a symlink to `release-tools/.travis.yml`
+
+To create a release, tag a certain revision with a name that
+starts with `v`, for example `v1.0.0`, then `make push`
+while that commit is checked out.
+
+It does not matter on which branch that revision exists, i.e. it is
+possible to create releases directly from master. A release branch can
+still be created for maintenance releases later if needed.
+
+Release branches are expected to be named `release-x.y` for releases
+`x.y.z`. Building from such a branch creates `x.y-canary`
+images. Building from master creates the main `canary` image.
+
+Sharing and updating
+--------------------
+
+[`git subtree`](https://github.com/git/git/blob/master/contrib/subtree/git-subtree.txt)
+is the recommended way of maintaining a copy of the rules inside the
+`release-tools` directory of a project. This way, it is possible to make
+changes also locally, test them and then push them back to the shared
+repository at a later time.
+
+Cheat sheet:
+
+- `git subtree add --prefix=release-tools https://github.com/kubernetes-csi/csi-release-tools.git master` - add release tools to a repo which does not have them yet (only once)
+- `git subtree pull --prefix=release-tools https://github.com/kubernetes-csi/csi-release-tools.git master` - update local copy to latest upstream (whenever upstream changes)
+- edit, `git commit`, `git subtree push --prefix=release-tools git@github.com:<user>/csi-release-tools.git <my-new-or-existing-branch>` - push to a new branch before submitting a PR
