+## Numbers to Words
+
+This project creates an API implemented in PHP and which requires installing a third party library.
+
+### Project file structure
+
+The GitHub project has the file structure that Nimbella uses to deploy the project with minimal configuration.
+- There is a single API implemented in [./packages/default/n2w](./packages/default/n2w).
+- The required library is specified in [./packages/default/n2w/composer.json](./packages/default/n2w/composer.json).
+- There is a [`build.sh`](./packages/default/n2w/build.sh) to install the required library during a Nimbella project deployment.
+
+### Deploy this project to the Nimbella Cloud
+
+If you have the [Nimbella command line tool called `nim`](https://docs.nimbella.com/cli) installed, you can deploy this project directly from GitHub. Or, you can clone this repository and deploy from the clone.
+
+- To deploy from GitHub
+
+  `nim project deploy github:nimbella/demo-projects/numbers-to-words`
+
+- If you have cloned the repository
+
+  `nim project deploy /path/to/numbers-to-words`
+
+The output of this command will include a link to where the application is running in the cloud for your account.
