The following will get way more than just recipe code, but it _will_ get the

More detailed instructions can be found [here](https://chromium.googlesource.com/infra/infra/+/master/doc/source.md).
Most of the functionality for recipes comes from `recipe_modules`, which are

### The infra config repository
The [infra](https://flutter.googlesource.com/infra/+/refs/heads/main) repository contains
configuration files for the dashboard, builder groups, scheduling, and
individual builders. Edits to this may require changes other internal Google
repositories - e.g., to change the operating system or number of machines. If
you want to do that, file an [infra ticket](https://github.com/flutter/flutter/wiki/Infra-Ticket-Queue)
with your proposed changes.
Each configuration file in that repository has a link in the top comments to a
schema that describes available properties.
