+# Cypress CLI source
+
+This folder is used to build Cypress NPM module.
+
+## Building
+
+See `scripts/build.js`. Note that the built NPM package will include [NPM_README.md](NPM_README.md) as its public README file.
+
+## Testing
+
+To build and test an NPM package:
+
+- `npm install`
+- `npm run build`
+
+This creates `build` folder.
+
+- `cd build; npm pack`
+
+This creates an archive, usually named `cypress-<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
+npm i ~/git/cypress/cli/build/cypress-3.1.5.tgz --ignore-scripts
+```
+
+Which installs the `tgz` file we have just built from folder `~/git/cypress/cli/build`.
