-Each image below is available in a **uv variant** that uses [uv](https://docs.astral.sh/uv/) with
-a relocatable venv (`/workspace/axolotl-venv`) instead of Miniconda + pip. Append `-uv` to the image name

+Each image below ships a **uv variant** that uses [uv](https://docs.astral.sh/uv/) with a relocatable venv

+**We recommend switching to the `-uv` images early.** In the near future we will publish the uv-based
+build to the non-uv tags as well. The non-uv names will continue to work, but they will start serving
+the uv image.
