+# Cypress
+
+## Setup
+
+Ensure you use the same `cypress` version in `node-packages.json` as the version of the cypress-binary provided by flake.nix.
+
+`default.nix`, `node-env.nix` and `node-packages.nix` can be updated by:
+
+```bash
+cd frontend/nix/tools/cypress
+
+ nix run ../../../..#pkgs.nodePackages.node2nix -- -i node-packages.json
+```
+
+## Usage
+
+```bash
+cd frontend/submission
+
+nix run ../..#cypress -- run   ## ci run
+nix run ../..#cypress -- open  ## gui
+```
