+# Composite buildpack release artifact
+
+This is a buildpack release artifact that contains everything needed to package and publish a composite buildpack. Composite buildpacks are a logic grouping of other buildpacks.
+
+It contains the following files:
+
+* `buildpack.toml` - this is needed because it contains the buildpacks and ordering information for the composite buildpack
+* `package.toml` - this is needed because it contains the dependencies (and URIs) that let pack know where to find the buildpacks referenced in `buildpack.toml`.
+  * `package.toml` can contain targets (platforms) for multi-arch support
+* `build/buildpack.tgz` - this is added because it is referenced in `package.toml` by some buildpacks
+
+## package locally
+
+To package this buildpack to local .cnb file(s) run the following.
+
+```
+pack buildpack package mybuildpack.cnb --format file --config package.toml
+```
+
+## package and publish to a registry
+
+To package this buildpack and publish it to a registry run the following.
+
+* Note that as of pack v0.38.2 at least one target is required in package.toml or on the command line when publishing to a registry with `--publish`.
+
+* replace SOME-REGISTRY with your registry (e.g. index.docker.io/yourdockerhubusername)
+* replace SOME-VERSION with the version you want to publish (e.g. 0.0.1)
+
+```
+pack buildpack package SOME-REGISTRY/mybuildpack:SOME-VERSION --format image --config package.toml --publish
