 ```bash
-nix build github.com:OpenGen/nix#ociImgBase

+## Packages
+
+### `.#sppl`
+
+Python [library by ProbSys](https://github.com/probsys/sppl) packaged for python3.9 .
+
+### `.#loom`
+
+Implementation of [CrossCat in Python](https://github.com/posterior/loom). NOTE: this ONLY builds for `x86_64` architectures and only runs on linux, because it depends on
+platform-dependent `distributions`.
+
+Your options are:
+
+```bash
+nix build '.#packages.x86_64-linux.loom'                      # same as `.#loom` if that is your OS/arch
+nix build './envs-flake#packages.x86_64-darwin.ociImgLoom'
+```
+
+If you are running on Mac silicon (`aarch64-darwin`), that OCI image will run but behavior is not defined or supported.
+
+#### `.#loom.morePackages.distributions`
+
+Native library for probability distributions in python used by Loom. NOTE: this ONLY builds for `x86_64` architectures and only runs on linux.
+
+#### `.#loom.morePackages.parsable`
+#### `.#loom.morePackages.pymetis`
+#### `.#loom.morePackages.goftests`
+#### `.#loom.morePackages.tcmalloc`
+
+Other upstream python packages required by Distributions and/or Loom.
