 This creates an archive, usually named `cypress-v<version>.tgz`. You can install this archive from other projects, but because there is no corresponding binary yet (probably), skip binary download. For example from inside `cypress-example-kitchensink` folder
 
 ```shell
-yarn add ~/{your-dirs}/cypress/cli/build/cypress-3.3.1.tgz --ignore-scripts
+yarn add ~/{your-dirs}/cypress/cli/build/cypress-v13.13.2.tgz --ignore-scripts
 ```
