# Download and Installation

First you need to set up your development environment and install ASEE Flow and the Camunda Modeler.

## Prerequisites

Make sure you have the following set of tools installed:

* Java JDK 17 or later (see [supported environments](/introduction/supported-environments))
* Apache Maven (optional — most IDEs bundle a Maven installation)
* A modern web browser (a recent Firefox, Chrome, or Microsoft Edge will work fine)
* An IDE for Java projects (for example IntelliJ IDEA, Eclipse, or VS Code)

## ASEE Flow

First, download a distribution of ASEE Flow. You can choose from different distributions for various application servers. In this tutorial we use the Apache Tomcat based distribution. Download it from the ASEE Flow customer repository (see [Accessing artifacts](/introduction/downloading-aseeflow#accessing-artifacts)).

After downloading the distribution, unpack it inside a directory of your choice. We will call that directory `$ASEEFLOW_HOME`.

Once you have successfully unpacked your distribution, execute the script named `start-camunda.bat` (for Windows users) or `start-camunda.sh` (for Unix users).

This script starts the application server and opens a welcome screen in your web browser. If the page does not open, go to [http://localhost:8080/camunda-welcome/index.html](http://localhost:8080/camunda-welcome/index.html).

## Camunda Modeler

Follow the instructions in the [Camunda Modeler](/installation/camunda-modeler) section.

## Next step

Continue to [project setup](/get-started/dmn/project-setup) to create your Java project.
