are canonical.

Each top folder represents an architecture. In that top folder, there's a
`README.md` file presenting the architecture as well as instructions to
minimally get Collapse OS running on it. Then, in the same folder, there are
auxiliary recipes for nice stuff built around that architecture.
The structure of those recipes follow a regular pattern: pre-collapse recipe
and post-collapse recipe. That is, instructions to achieve the desired outcome
from a "modern" system, and then, instructions to achieve the same thing from a
system running Collapse OS.
Installation procedures are centered around using a modern system to install
Collapse OS. This is the most useful instructions to have most pre-collapse and
post-collapse because even after the collapse, we'll interact mostly with modern
technology for many years.
Initially, those recipes will only be possible in a "modern" system, but as
tooling improve, we should be able to have recipes that we can consider
complete.
There are, however, recipes to write to different storage media, thus making
Collapse OS fully reproducible. For example, you can use `rc2014/eeprom` to
write arbitrary data to a `AT28` EEPROM.
The `rc2014` architecture is considered the "canonical" one. That means that
if a recipe is considered architecture independent, it's the `rc2014` recipe
folder that's going to contain it.
For example, `rc2014/eeprom` can be considered architecture independent because
it's much more about the `AT28` than about a specific z80 architecture. You can
adapt it to any supported architecture with minimal hassle. Therefore, it's
not going to be copied in every architecture recipe folder.
`rc2014` installation recipe also contains more "newbie-friendly" instructions
than other installation recipes, which take this knowledge for granted. It is
therefore recommended to have a look at it even if you're not planning on using
a RC2014.
