 Various examples for different nix flakes, useful for `nix develop`
+
+Usage
+-----
+
+Several options for using these flakes:
+
+1. Copy the flake.nix file locally, use nix develop
+2. Use in place with nix develop. For example, for hugo:
+
+```sh
+$ nix develop https://git.lerch.org/lobo/nix-flake-examples/archive/master.tar.gz?dir=/hugo
+```
+
+3. Use with [devenv](https://devenv.sh/). Again, hugo example. Add this to `.envrc`:
+
+```sh
+if ! has nix_direnv_version || ! nix_direnv_version 3.0.6; then
+  source_url "https://raw.githubusercontent.com/nix-community/nix-direnv/3.0.6/direnvrc" "sha256-RYcUJaRMf8oF5LznDrlCXbkOQrywm0HDv1VjYGaJGdM="
+fi
+
+use flake 'https://git.lerch.org/lobo/nix-flake-examples/archive/master.tar.gz?dir=/hugo'
+```
