 View Paths
 ----------
 
-TODO...
+When rendering the view for a request, the controller needs to resolve where to find each of the directories are located.
+
+We are able to modify the order these locations are resolved by using `prepend_view_path` and `append_view_path`.
+
+This allows us to add new paths to the beginning or end of the list used to resolve these paths.
+
+### Prepend view path
+
+This can be helpful for example, when we want to prepend a different directory for subdomains.
+
+We can do this by using:
+
+```prepend_view_path "app/views/#{request.subdomain}"```
+
+Then our list becomes something like:
+
+```
+[
+  ~/rails_app/app/views/<subdomain>,
+  ~/rails_app/app/views,
+  # ...
+]
+```
+
+This will put the subdomain path at the beginning of the list.
+
+### Append view path
+
+Similarly, we can append paths:
+
+```append_view_path "app/views/direct"```.
+
+This will add ```app/views/direct``` and the end of lookup paths for views.
