# Generating a new application

Quarkus offers two main ways of generating a new application.

## Using the web page

Generating a new Quarkus application can be done directly by going to [code.quarkus.io](https://code.quarkus.io) and selecting the needed extensions, the build tool, and general information about our new project.



As seen in the screenshot above, we can specify multiple options for our new Quarkus application. These include the following:

* **Group:** Represents the owner of this application and is usually a company name.
* **Artifact:** A unique identifier for the application.
* **Build tool:** The preferred build tool can be either Maven or Gradle.
* **Version:** The generated project version.
* **Java version:** The Java version to be used.
* **Starter code:** Whether Quarkus will generate a started code.
* **Chosen extensions:** A list of the extensions to be used in the application.

Then, all we need to do is click the “Generate your application” button to download our source code as a zip file. We can also directly push the code to GitHub.
