OOTs and C++
"Out of Tree Modules (OOTs)" and "Writing blocks in C++" clearly have some overlap that needs to be sorted out, if someone wants to tackle that it would be awesome
Types of Blocks
There should be a new or existing beginner tutorial that includes the different types of blocks, like source/sink/sync/general
Where to Find Example Code
Throughout the tutorials, it is seemingly possible to build the examples yourself until you get into higher level blocks such as "symbol_sampling.grc" in the QPSK Mod and Demod Tutorial. This text could easily be linked to the .grc file used in the tutorial.
