+
+### Step 1
+
+Make a directory inside your "tessel-code" folder called "camera", change directory into that folder, and initialize a tessel project:
+
+`mkdir camera; cd camera; t2 init`
+
+### Step 2

+
+<div class="row">
+<div class="large-6 columns">
+
+Plug Tessel into your computer via USB, then plug the camera module into either of Tessel's USB ports. You will also need a [UVC compatible USB camera](https://tessel.io/modules#tessel-av).

+- Try connecting a button to your Tessel 2 and use it as a shutter. 
+- Use an USB storage drive to store many photos.
