+# Nix
+
+This repository uses Nix as the canonical local development and validation environment.
+
+## Enter The Shell
+
+```bash
+nix develop
+```
+
+## Command Map
+
+```bash
+nix run .#fmt
+nix run .#check
+nix run .#test
+nix run .#release-acceptance
+```
+
+Use `nix develop` before running narrower ad hoc cargo commands from this repo root.
