+This section gives step-by-step instructions along with photos to ensure you make the proper connections to your link box.
-\\
-\\
 **Step 1**
-\\
+Grab the two long USB-C cables from the headset and connect them to their respective slots on the Link Box (connect A to A, B to B).

+**Step 3**
+Connect the two Display Cables from the back of the link box to two available DisplayPort slots on your PC
+**Step 4**
+Once everything is properly connected to the link box, grab the 12v 3.0A AC Adapter, and connect it to the link box (connection is found on the side with the two USB 3.0 and DisplayPort cables), and connect the AC Adapter to an available wall outlet.

+The headset is now powered on! Time to install/run the necessary software.
 ==== Software ====
-A link to the source code can be found <provide URL to your code, probably saved in this DASL Wiki>.
+To get the headset running, you must install Varjo Base! Go to the following link:
-\\
-The goal of the code is <brief explanation>.  It works in the following way
+https://account.varjo.com/login
-\\
-----
+And login to DASL’s Varjo Base Account (For security purposes, the account information will only be provided in the lab. Account information will be located in the VR area)

 ==== Varjo Base ====
+Once the software has been installed properly, you should see the following:
+{{:varjobasesnip.png?nolink&800|}}
+Note: There are two types of tracking that the Varjo XR3 uses:
+  * Inside-Out Tracking
+    * Utilizes the Front-facing cameras to draw virtual boundaries around the player
+  * SteamVR
+    * Utilizes HTC Vive 2.0 Base Stations to track the position of the headset
+ **You can use either or, however, since our lab has Base Stations, we will use SteamVR**
+To change the tracking type, go to Varjo Base, click on System, and under Headset Tracking, change it to SteamVR.
+  * Calibration with SteamVR will not be shown in this tutorial. Tutorial for any headset utilizing SteamVR will be shown here (Add link for SteamVR calibration).
 ==== Connecting the Varjo XR3 to Unity ====
+In order to get our headset connected to Unity, we will require the following packages:
+  * SteamVR
+  * Varjo's Unity SDK
+Before installing the above-mentioned packages, please create a new Unity 2020+ 3D project and name it **Varjo_XR3_Intro**.
+Once the project has opened, go to the Asset Store, download SteamVR (if not already downloaded), and import it into your project.
+Once SteamVR has finished installing, you may now install the Varjo SDK for Unity
+Copy this Github link: https://github.com/varjocom/VarjoUnityXRPlugin
+Go back to Unity and press Window. Then scroll down to Package Manager.
+When the package manager opens, press the top left (+) icon and select add package from git URL. Paste the above GitHub link into the text box and press add.
+After a few minutes, the package should have installed the Varjo SDK into Unity!
+In the Asset section, search for the Player GameObject and drag it into the Hierarchy.
+And finally, hit play and put on the headset!
