The RFCs located here define the mechanics of Gaia in a great detail in order to reach consensus by all the participants.
How does that work?
The RFCs located here are first introduced as Issues under the Gaia repository located here: Gaia on Github
Then, a PR is opened up in the documentation section of Gaia thus enabling an interactive discussion about the RFC. It is done thus so changes and edits aren’t lost or could be easily reverted allowing for an organic grow of an RFC.
For an example, please take a look at the first RFC defining the Distributed execution model located here: RFC: Distributer Pipeline execution via Workers
