# Adding data warehouse projects

Adding a new project is the first task you need to undertake in order to work with Qlik Compose.

There are two types of project:

* Data Warehouse - for ingesting data from multiple sources and creating analytics-ready data marts.
* Data Lake - for ingesting data from multiple sources and moving it to a storage system for analytics.

This topic guides you through the steps required to set up a data warehouse project. For instructions on setting up a Data Lake project, see [Adding data lake projects](https://help.qlik.com/en-US/compose/December2024/Content/ComposeDWDL/Main/DL/Projects/add_projects.htm).

You can set up as many projects as you need, although the ability to actually run tasks is determined by your Compose license.
