Different templates receive different types of contexts. We should have API documentation for the contexts either in this repo or ZolangTemplates

You can see all the standard names of stencil files in ZolangTemplates

NOTE: It's very good to see how the contexts are created.

In this repo under Sources -> ZolangCore -> Frontend -> Models -> Nodes

You can see the objects that generate these contexts that are passed on to the template engine.

Alternatively you could search the repo for getContext function declarations to investicate how they are created.
