+### devenv
+
+Add the project input into the `devenv.yaml` file:

+```yml
+inputs:
+  iecs:
+    url: github:sestrella/iecs
+    overlays:
+      - default
+```
+
+To install the binary, add it to the `packages` section in the `devenv.nix`
+file:
+
+```nix
+packages = [ pkgs.iecs ];

+### flake
+
+Add the project input into the `flake.nix` file:

+
+#### Using it as an overlay
+
+Add the project overlay to `nixpkgs`:
+
+```nix
+pkgs = import nixpkgs {
+  inherit system;
+  overlays = [ iecs.overlays.default ];

+#### Using it as a package
