Add dependencies section.

This can be found in the quickstart guide but is worth putting front and
center here, especially for the things we don't mention in the

 If you don't already have a Yocto project that you want to add OTA to, you can use the https://docs.atsgarage.com/quickstarts/raspberry-pi.html[HERE OTA Connect Quickstart] project to rapidly get up and running on a Raspberry Pi. It takes a standard https://www.yoctoproject.org/tools-resources/projects/poky[poky] distribution, and adds OTA and OSTree capabilities.
 
+=== Dependencies
+
+In addition to the link:https://www.yoctoproject.org/docs/current/ref-manual/ref-manual.html#required-packages-for-the-build-host[standard Yocto dependencies], meta-updater generally requires a few additional dependencies, depending on your use case and target platform. To install these additional packages on Debian/Ubuntu, run this:
+
+....
+sudo apt install cpu-checker default-jre parted
+....

+To build for https://github.com/advancedtelematic/meta-updater-minnowboard[Minnowboard] with GRUB, you will also need to install https://github.com/tianocore/tianocore.github.io/wiki/OVMF[TianoCore's ovmf] package on your host system. On Debian/Ubuntu, you can do so with this command:

+sudo apt install ovmf

 Your images will also need network connectivity to be able to reach an actual OTA backend. Our 'poky-sota' distribution does not mandate or install a default network manager but our supported platforms use the `virtual/network-configuration` recipe, which can be used as a starting example.
