+2. All the sub-projects are registered as submodules. To initialize them, call:
+ $ make submodules-init
+
+3. Apply patches from `patches/<sub-project>/*` to respective submodules via:
+ $ make patches-import
+
+ This will result in creation of:
+ - a tag called `armband-workbench-root` at the same commit as Fuel@OPNFV
+ hard sets in `build/config.mk` (inside fuel submodule);
+ - a new branch `armband-workbench` which will hold all the armband work.
+ Then each patch is applied on this new branch with `git-am`.
+
+4. Modify sub-projects for whatever you need.
+ Commit your changes when you want them taken into account in the build.
+
+5. Build with:
+ $ make build
+
+6. Re-create patches via:
+ $ make patches-export
+
+ Each commit on `armband-workbench` branch of each subproject will be
+ exported to `patches/subproject/` via `git format-patch`.
+
+ NOTE: DO NOT commit changed submodules. Remember to commit only patches!
+
+ Commiting changed submodules (`git diff` will list something like:
+ `Subproject commit: {hash}`) will break the repo, as the new commit hash
+ is non-existant in the upstream repo, hence anybody cloning the repository
+ later will fail on `make submodules-init`.
+
+7. Clean workbench branches and tags with:
+ $ make submodules-clean
