How to write the assemblies, tracks and settings a JBrowse session is built
from. They are the same objects in a served `config.json`, in a `jbrowse` CLI
command, and pasted into a running JBrowse Web or Desktop, so a guide here
applies wherever you run it. For copy-paste recipes, see the [](https://jbrowse.org/jb2/docs/cookbook).
