Subject: [PATCH 1/2] add a note on setting object references via context
In my subgraph I needed a reference between the factory and template. I ended up passing the factoryID to the template with context.

## Start Blocks
The `startBlock` is an optional setting that allows you to define from which block in the chain the data source will start indexing. Setting the start block allows the data source to skip potentially millions of blocks that are irrelevant. Typically, a subgraph developer will set `startBlock` to the block in which the smart contract of the data source was created.
