+For a full source checkout do
+
+ # git submodule update
+
+Or do a selective checkout and build can be done via
+
+ # git submodule update PACKAGE_A
+ # cd PACKAGE_A
+ # pbuild
+
+A cross architecture build can be invoked via
+
+ # pbuild --preset cross_aarch64
+
+for example. Please note that this works only for package sources which support cross
+architecture building. This is not using any emulator, but must be natively supported.
+
+You may build using qemu if that fails via
+
+ # pbuild --vm-type=qemu --preset aarch64
+
+for example.
