How does gRPC work?: Doesnt explain the g

[stationname]

1. Doesn't explain the g

2. The provided image does not show gRPC, but RPC ( this will confuse beginners )
   

3. The second image then has gRPC in it's title, suggesting that the "non-overall flow of gRPC" is already being explained.

4. In the steps section, gRPC appears to be an active component that can do things. This opposes the previous (blurry) explanation that it's a concept rather than a thing.
