 ## Devcontainers and VS Code support
 
-The R-enabled images in this repository (`latest`, `minimal`, `osgeo`, `pythonr`) fully support VS Code Devcontainers. When you launch a devcontainer using one of these images:
-
-* **Alternative R Frontend (arf)** is pre-installed system-wide to `/usr/local/bin/arf`, providing a highly improved interactive R shell with bracketed paste, multi-line editing, and syntax highlighting.
-* VS Code is automatically configured via container metadata to use `arf` as the default R terminal frontend out-of-the-box.
-* For interactive convenience, the `R` command is aliased system-wide (`alias R=arf`) in bash terminals. Typing `R` in an interactive shell automatically routes to the `arf` console. (This is safe as shell aliases only apply in interactive bash shells and do not interfere with standard non-interactive scripts running package installations or build pipelines).
