-If you need to add another subproject, you can do it with `git submodule`. Make sure that you specify branch (with `-b`), short name (with `--name`) and point it to `upstream/*` directory, i.e.:
-```
-git submodule -b stable/8.0 add --name fuel-web git@github.com:openstack/fuel-web.git upstream/fuel-web

+Fuel@OPNFV submodule patch development
+--------------------------------------
+Fuel-submodules (fuel-astute, ... , fuel-ui) patches also reside in Armband,
+like previously described patches that are applied to Armband submodules,
+but they are not directly applied to any submodule in Armband.
+Instead, they are copied (staged) to Fuel@OPNFV submodule, which will
+automatically pick them up and apply them to its own submodules
+(fuel-astute, ... , fuel-ui) during ISO build.
+
+The following helpers are available for working with patches for
+Fuel-submodules (fuel-astute, ... , fuel-ui):
+
+1. Clean Fuel-submodules (fuel-astute, ... , fuel-ui) patches
+ $ make fuel-patches-clean
+
+2. Import Fuel-submodules staged patches
+ $ make fuel-patches-import
+
+3. Export Fuel-submodules patches
+ $ make fuel-patches-export
