 ## Step 3: Clone the repos
 
-Right now there are 3 repos you need:
-* Tutorial files
+There are 2 repos you need:
 * IP6 (IP-specific components)
 * Athena detector
 
 ```bash
-git clone https://eicweb.phy.anl.gov/EIC/tutorials/ip6_tutorial_1.git
 git clone https://eicweb.phy.anl.gov/EIC/detectors/athena.git
 git clone https://eicweb.phy.anl.gov/EIC/detectors/ip6.git
+ln -s ../ip6/ip6 athena/ip6
 ```
 
-Initially we will just be using the first repo. So we will com back to the latter two later on.
+In part 1 of the tutorial we will be mostly using files from a tutorial repo. 
+Later on, we will com back to these detector repositories.
 
+## Step 4: Looking at the geometry
+
+Before moving on to part 1, let's generate the geometry in a root file:
+
+
+```
+cd athena
+dd_web_display --export athena.xml
+```
+
+This will generate the file `detector_geometry.root`, which you should copy to your local machine.
+Then open the [web viewer](https://eic.phy.anl.gov/geoviewer/), click on the `...` and open the local root file.
+
