+Choosing Your CI Solution
+=========================
+
+FoundriesFactories supports two different modes for building Targets.
+
+FoundriesFactory Managed
+------------------------
+
+Every Factory includes a `containers.git` hosted at source.foundries.io.
+This works out of the box and changes pushed here will be built automatically by our CI system and produce Targets that can be deployed to your device(s).
+
+To get started with the Foundriesio managed solution you'll need to:
+
+- :ref:`Install Fioctl <gs-install-fioctl>` in order to work with source.foundries.io.
+- :ref:`Build and deploy <gs-building-deploying-app>` your first application.
+
+Self-hosted
+-----------
+
+The self-hosted option works well for people wanting more control of their workflows.
+It works great with products like GitHub.
+There is a one-time setup that takes about 30 minutes.
+
+To get started with the self-hosted option, you'll need to follow the steps outlined in the :ref:`Custom CI <ug-custom-ci-for-apps>` guide.
