-This Debian-based image allows you to easily build cross-platform images.
+This Debian-slim-based image allows you to easily build cross-platform images.
 It's been tested with GitLab CI on gitlab.com, but it should work anywhere that docker-in-docker already works, and with a `binfmt_misc` enabled kernel.
 
+The `ixdotai/docker-buildx-qemu` image supports the following architectures:
+* `amd64`
+* `arm64`
+
+The following additional tools are installed, to be used in your pipelines:
+* `curl`
+* `git`
+* `jq`
+
 ## Example Usage
 
 This GitLab example should give you an idea of how to use the image.
