 ### Subfolders

+Sometimes the application under test and the Cypress end-to-end tests may have separately defined dependencies. In the example below, Cypress has its own `package.json` file in a subfolder:
 
 ```text
 root/
   e2e/
     (code for installing and running Cypress tests)
     package.json
     package-lock.json
-    cypress.json
-    cypress
+    cypress.config.js
+    cypress/
 
   (code for running the "app" with "npm start")
   package.json
-  yarn.lock
+  package-lock.json
 ```
 
-In that case you can combine this action with [bahmutov/npm-install](https://github.com/bahmutov/npm-install) action to install dependencies separately.
+In this case you can first install the dependencies for the application (`npm ci`), then start the application server (`npm start`) before calling `cypress-io/github-action` to install the dependencies for Cypress and to run Cypress. You may also need to use the [wait-on](#wait-on) parameter to make sure that the app server is fully available.
