+Building and Deploying Application
+==================================
+
+.. tip::
+
+   When your Factory is first created, a single branch (``main``) is created.
+   We suggest using a ``devel`` branch for development.
+   Once changes are tested and approved, migrate them to ``main``.
+
+Clone and enter your ``containers.git``:
+
+.. prompt:: bash host:~$
+
+    git clone -b devel https://source.foundries.io/factories/<factory>/containers.git
+    cd containers
+
+Your ``containers.git`` repository is initialized with a simple application example in ``shellhttpd.disabled``.
+
+.. tip::
+
+  Directory names ending with ``.disabled`` in ``containers.git`` are **ignored** by the FoundriesFactory® CI.
+
+Move the entire application folder ``shellhttpd.disabled`` to ``shellhttpd``:
+
+.. prompt:: bash host:~$
+
+    git mv shellhttpd.disabled/ shellhttpd
+
+Commit your changes with a message:
+
+.. prompt:: bash host:~$, auto
+
+    host:~$ git commit -m "shellhttpd: add application"
+
+Push all committed modifications to the remote repository:
+
+.. prompt:: bash host:~$, auto
+
+    host:~$ git push
+
+**Example Output**:
+
+.. prompt:: text
+
+     Enumerating objects: 6, done.
+     Counting objects: 100% (6/6), done.
+     Delta compression using up to 16 threads
+     Compressing objects: 100% (5/5), done.
+     Writing objects: 100% (5/5), 795 bytes | 795.00 KiB/s, done.
+     Total 5 (delta 0), reused 0 (delta 0), pack-reused 0
+     remote: Trigger CI job...
+     remote: CI job started: https://ci.foundries.io/projects/<factory>/lmp/builds/4/
+     To https://source.foundries.io/factories/<factory>/containers.git
+        daaca9c..d7bc382  main -> main
+
+.. note::
+
+   The output of ``git push`` indicates the start of a new CI job.
+
+Once your changes to the :term:`containers.git` repository were pushed, the FoundriesFactory® CI automatically started a new ``container-main`` build.
+Go to https://app.foundries.io, select your Factory and click on :guilabel:`Targets`:
+
+The latest **Target** named :guilabel:`containers-main` should be the CI job you just created.

+
+   FoundriesFactory Targets
+
+Your device is configured to always download the latest **Target** version with a specific ``tag``.
+
+By default, devices run **all** applications defined in the ``containers.git`` repo.
+This behavior can be changed by enabling only specific applications.
+This will be covered this in more detail later.
+
+When the container build finishes, the device will download and start the shellhttpd application.
+
+Check the device status on the :guilabel:`devices` page and wait the ``shellhttpd`` on :guilabel:`APPS` and the green light on :guilabel:`STATUS`.

+
+Testing the Container
+^^^^^^^^^^^^^^^^^^^^^
+
+``curl`` is not available on your device, instead run ``wget`` to test the container like so:
+
+.. prompt:: bash device:~$, auto
+
+    device:~$ wget -qO- 127.0.0.1:8080
+
+::
+
+     Hello world
+
+You can also test the container from an external device connected to the same network, such as your computer.
+
+.. prompt:: bash host:~$, auto
+
+    host:~$ #Example curl 192.168.15.11:8080
+    host:~$ curl <device IP>:8080
+
+::
+
+     Hello world
+
+You can follow a more detailed documentation by following the next section **Tutorials** starting with :ref:`tutorial-gs-with-docker`
