+=
+
+`image` is a set of Go libraries aimed at working in various way with
+containers' images and container image registries.
+
+The containers/image library allows application to pull and push images from
+container image registries, like the upstream docker registry. It also
+implements "simple image signing".
+
+The containers/image library also allows you to inspect a repository on a
+container registry without pulling down the image. This means it fetches the
+repository's manifest and it is able to show you a `docker inspect`-like json
+output about a whole repository or a tag. This library, in contrast to `docker
+inspect`, helps you gather useful information about a repository or a tag
+without requiring you to run `docker pull`.
+
+The containers/image library also allows you to translate from one image format
+to another, for example docker container images to OCI images. It also allows
+you to copy container images between various registries, possibly converting
+them as necessary, and to sign and verify images.
+
+## Command-line usage
+
+The containers/image project is only a library with no user interface;
+you can either incorporate it into your Go programs, or use the `skopeo` tool:
+
+The [skopeo](https://github.com/projectatomic/skopeo) tool uses the
+containers/image library and takes advantage of many of its features,
+e.g. `skopeo copy` exposes the `containers/image/copy.Image` functionality.
+
+## Dependencies
+
+This library does not ship a committed version of its dependencies in a `vendor`
+subdirectory.  This is so you can make well-informed decisions about which
+libraries you should use with this package in your own projects, and because
+types defined in the `vendor` directory would be impossible to use from your projects.
+
+What this project tests against dependencies-wise is located
+[in vendor.conf](https://github.com/containers/image/blob/master/vendor.conf).
+
+## Building
+
+If you want to see what the library can do, or an example of how it is called,
+consider starting with the [skopeo](https://github.com/projectatomic/skopeo) tool
+instead.
+
+To integrate this library into your project, put it into `$GOPATH` or use
+your preferred vendoring tool to include a copy in your project.
+Ensure that the dependencies documented [in vendor.conf](https://github.com/containers/image/blob/master/vendor.conf)
+are also available
+(using those exact versions or different versions of your choosing).
+
+This library, by default, also depends on the GpgME and libostree C libraries. Either install them:
+```sh
+Fedora$ dnf install gpgme-devel libassuan-devel libostree-devel
+macOS$ brew install gpgme
+```
+or use the build tags described below to avoid the dependencies (e.g. using `go build -tags …`)
+
+### Supported build tags
+
+- `containers_image_openpgp`: Use a Golang-only OpenPGP implementation for signature verification instead of the default cgo/gpgme-based implementation;
+the primary downside is that creating new signatures with the Golang-only implementation is not supported.
+- `containers_image_ostree_stub`: Instead of importing `ostree:` transport in `github.com/containers/image/transports/alltransports`, use a stub which reports that the transport is not supported. This allows building the library without requiring the `libostree` development libraries.
+
+  (Note that explicitly importing `github.com/containers/image/ostree` will still depend on the `libostree` library, this build tag only affects generic users of …`/alltransports`.)
+
+## Contributing
+
+When developing this library, please use `make` (or `make … BUILDTAGS=…`) to take advantage of the tests and validation.
