 ## Usage
 
 > [!NOTE]
-> If you are new to Nextflow and nf-core, please refer to [this page](https://nf-co.re/docs/usage/installation) on how to set-up Nextflow. Make sure to [test your setup](https://nf-co.re/docs/usage/introduction#how-to-run-a-pipeline) with `-profile test` before running the workflow on actual data.

-To run the pipeline on real data, input data needs to be acquired. Concretely, satellite imagery, water vapor data, a digital elevation model, endmember definitions, a datacube specification, and a area-of-interest specification are required. Please refer to the [usage documentation](https://nf-co.re/rangeland/usage) for details on the input structure.
