 ### Supported archives
 
-Currently, when specifying a URI to a buildpack or lifecycle, only `tar` or `tgz` archive types are supported.
+A URI to a buildpack or lifecycle can use one of the following sources:
+
+- **Archives:** `.tar` or `.tgz` files, either local or remote.
+- **Docker images:** the `docker://` URI scheme.
+
+**Examples**
+
+- `file:///path/to/buildpack.tgz`
+- `https://example.com/buildpack.tar`
+- `docker://example/buildpack:latest`
