-TODO: cover creating a ADUrl based Area detector generic IOC based
-on the ADSimDetector one. (point at a public web cam)
+The example IOC used a ADSimDetector, we will make a similar IOC that uses a
+ADUrl to get images from a web cam.
+
+Create a New Generic IOC project
+--------------------------------
+
+Much like creating a new beamline we have a template project that can be used
+as the starting point for a new generic IOC. Again we will create this in
+your personal GitHub user space.
+
+TODO: the following steps to create a new generic IOC project will be automated
+using and ``ec`` command.
+
+#.  Create a new, completely blank repository in your GitHub account
+    called ``ioc-adurldetector``. To do this got to https://github.com/new
+    and fill in the details as per the image below. Click
+    ``Create repository``.
+
+#.  Clone the template repo locally and rename from ioc-template to ioc-adurldetector
+
+    .. code-block:: bash
+
+        git clone [email protected]:epics-containers/ioc-template.git
+        mv ioc-template ioc-adurldetector
+        cd ioc-adurldetector
+
+#.  Add your new repo to your VSCode workspace and take a look at what you
+    have.
+
+    From the VSCode menus: File->Add Folder to Workspace
+    then select the folder ioc-adurldetector
+
+#.  Push the new repo back to a the new repo on github
+
+    .. code-block:: bash
+
+        git remote rm origin
+        git remote add origin [email protected]:<YOUR USER NAME>/ioc-adurldetector.git
+        git push origin main
