+## Usage
+
+### Repository with a single crate (not a workspace)
+
+Create a `flake.nix` in the root of the repository with the following contents:
+
+``` nix
+{
+  inputs = { rust = { url = "git+https://git.stranger.systems/nix/Rust"; }; };
+  description = "Simple Test Package";
+
+  outputs = { self, nixpkgs, rust }:
+    rust.single {
+      crateName = "CRATE_NAME";
+      src = ./.;
+    };
+}
+```
+
+Optionally create a `.envrc` in the root of the repository with the following contents:
+
+``` nix
+use flake
+```
