+Development Environment
+***********************
+
+ROILoc relies on Nix_ and Devenv_.
+
+.. _Nix: https://nixos.org/download/
+.. _Devenv: https://devenv.sh
+
+**Step 1**: Install Nix_:
+::
+
+    sh <(curl -L https://nixos.org/nix/install) --daemon
+
+**Step 2**: Install Devenv_:
+::
+
+    nix-env -iA devenv -f https://github.com/NixOS/nixpkgs/tarball/nixpkgs-unstable
+
+**Step 3**: 
+::
+
+    devenv shell
+
+That's it :)
+
+If you want something even easier, install direnv_ and
+allow it to automatically activate the current env (``direnv allow``).
