+Are you new to Galaxy for Earth System sciences, or returning after a long time, and looking for help to get started? Take a [__guided tour__](https://training.galaxyproject.org/training-material/topics/climate/tutorials/earth_system/tutorial.html){:target="_blank"} through a detailed tutorial on the Galaxy Training Network.
+
+# Training
+
+We are working in close collaboration with the [__Galaxy Training Network (GTN)__](https://training.galaxyproject.org){:target="_blank"} to develop training materials of data analyses based on Galaxy. If you want to know more about the GTN or how to become part of the Galaxy community, check the videos below!
+
+**Training material**
+
+All relevant materials for Earth System, Environment and Biodiversity data analysis will be available within the GTN. You can search for them within the GTN by writing **earth-system** in the search bar or directly acces our full [set of tutorials](https://training.galaxyproject.org/training-material/search2?query=earth-system).
+A sample of the different tutorials that you can find below but many more are available:

# Workflows
To orchestrate tools and help users with their analyses, several [workflows](https://galaxyproject.org/learn/advanced-workflow/){:target="_blank"} will be available. They formally orchestrate tools in a defined order and with defined parameters, but they are customizable (tools, order, parameters).
