 crossbuilder
 ```
 
+Crossbuilder by default builds for armhf architecture. If a device is connected, it should detect the devices architecture. In case for some reason the architecture needs to be explicitely specified, it can be set like this:
+```bash
+crossbuilder --architecture=arm64
+```
+
+To be able to install the deb on the device after building, the devices sudo password needs to be provided:
+```bash
+crossbuilder --password=PASSWORD
+```
+We can specify specific lxd images for the build process. This can be useful e.g. when building for specific target releases like 20.04. 
+```bash
+crossbuilder --lxd-image=ubuntu:20.04
+```
+
 Change a line of code and type crossbuilder again to re-build and re-deploy.
