# Creating Your Application ## Generating your Application First, we need to [install the Blueprint command-line interface (cli)](/quick-start/getting-started.md#installation). The cli makes it easier to start a new Blueprint application, and implement different components of the application. When installing the cli, you want to install it globally. Now, use the installed [blueprint cli](https://github.com/onehilltech/blueprint-cli/) to generate a new application. ```bash blueprint new super-rentals ``` The cli will generate a new Blueprint application in the `super-rentals` directory. It will also install the node modules for the application. ## Starting your application Let's make sure the `super-rentals` application generated correctly. Change to the newly generated directory, and run the application as follows: ```bash node ./app ``` This will start the Blueprint application in development mode, and make it available at . If you want to run the Blueprint application in a different environment mode, then use the `NODE_ENV` environment variable. For example, if you want to run the application in a `production` environment, then use the following command: ```bash NODE_ENV=production node ./app ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
