 ### articulate/elixir vs articulate/articulate-elixir
 
 `articulate/articulate-elixir` are the legacy Docker images. These run as root and
-include additional software not always needed. Use `articulate/elixir` where possible
-and install your own software with `install_packages`.
-
-## Creating a new image
-
-The easiest way to create a new image is to copy an existing one and change the
-base image. If creating from scratch, the images need the following:
-
-* Everything listed in [What's included](#whats-included)
-* `make` for internal tooling.
-* A _service_ user and group with a GID and UID of 1001. This should be the default
-  user.
-* A _/service_ directory as the default working directory.
+include additional software not always needed. `articulate/elixir` runs as a
+non-root _service_ user and provides `install_packages` for adding software.
