+_A collection of common devshell modules specified via [`numtide/devshell`][devshell]._
+
+## Why?
+
+- Avoid repetition and reuse common best practices.
+- Provide a collection of components to "kill the toil" in the devshell in different scenarios.
+- Integrate DevShell concerns with the wider config management in `nix`: cross-reference variables.
+
+## Usage
+
+This is a prototype: consult usage with your Resident SRE.
